Caricatura_linhas_pb_versao_2

Use the exact face and likeness from the reference/input photo only, keeping 100% of all real physical features as the foundation. Preserve precisely the same skull and bone structure, eye shape and eye distance, nose shape and tip, mouth shape and lips, jawline definition, cheekbone height and shape, chin structure, ear shape and size, eyebrow shape and arch, hairline position and hairline shape, skin tone and skin texture. The artistic caricature treatment applies exaggeration to these REAL features—making distinguishing characteristics slightly more pronounced and stylized—but WITHOUT fundamentally changing the person's identity or structure. The exaggeration should be subtle and sophisticated (not cartoonish), emphasizing natural characteristics while maintaining recognizability. For example: If the reference shows narrow eyes, slightly narrow them further; if the nose is long, render it with slightly enhanced definition and angularity; if the jawline is strong, make it slightly more pronounced; if the ears are prominent, emphasize them slightly; if there are natural furrows, deepen them subtly for expression. Do not alter the fundamental facial structure. Do not change gender or ethnicity. Do not make the person unrecognizable. The result must remain clearly the same individual from the photograph, only stylized through artistic caricature technique and subtle exaggeration of natural distinguishing characteristics. Preserve the exact hairstyle from the reference photo: same hair length measured precisely, same hair volume and density, same hair direction and flow, same hair color rendered in grayscale values. Do not cut, layer, restyle, trim or modify the hairline. Hair should be rendered as short and curled/textured as shown in reference, with appropriate ink cross-hatching to convey texture and volume. Keep the same gender presentation and ethnicity as clearly shown in the reference image. Do not change body type, height, shoulder width, or body proportions. The final caricature must remain unmistakably the same real person from the photograph, only stylized through artistic technique and subtle feature exaggeration. MAIN PROMPT: Create a sophisticated hand-drawn black and white caricature portrait in fine ink using cross-hatching technique. The drawing should be based on the exact person from the uploaded reference photo, maintaining 100% facial fidelity while applying subtle, artistic caricature exaggeration. The subject is rendered as a middle-aged male with a serious expression and slightly exaggerated structural features that emphasize his distinguishing characteristics. Render the face with cross-hatching and fine ink line work: use closely-spaced parallel lines and cross-hatched patterns to create tonal values, shadows and depth. The technique should be refined and professional, resembling traditional fine art caricature or classical ink portraiture rather than cartoon or comic style. Each facial feature should be executed with careful attention to line quality, spacing and value relationships. The facial features should reflect the reference photo with subtle artistic exaggeration applied: render the eyes as somewhat narrowed or intensely focused if the reference shows natural narrowness, enhance this characteristic subtly; the eyebrows should be clearly defined with possible subtle exaggeration of furrow or arch as present in reference; the nose should display its actual shape with slightly enhanced definition and angularity; the jaw should reflect its true structure with possible subtle elongation or emphasis if that is a distinguishing characteristic; the ears should be rendered at their actual size and shape with possibility of slight emphasis if prominent in reference; the mouth should show its natural expression, possibly slightly exaggerated if that is characteristic; facial structure should show subtle exaggeration that enhances character without distorting identity. The hairline and hair texture should match the reference exactly: short, curled or textured hair rendered with fine cross-hatching to convey the actual hair type, volume and direction visible in the photo. Do not add or remove hair; only render it in the medium of ink and cross-hatch. Compose the portrait as a straightforward head-shot with slight head tilt (as natural in reference), showing upper torso and shoulders. Position the head and neck in the center or slightly off-center of the frame. Include shoulders and upper chest, with formal suit jacket with sharp collar clearly rendered. The suit should be textured through careful cross-hatching, showing fabric detail and formal tailoring. Render all clothing in black and white values, no color additions. The background should be completely clean white, with no texture, pattern, or additional elements. Only the figure should occupy the composition, creating stark contrast between the detailed figure and empty background space. The overall tone should be serious, dignified and professional—a refined fine art caricature suitable for gallery exhibition or professional portraiture context. The expression should be neutral to serious, conveying confidence and professionalism. The technique should demonstrate mastery of pen and ink, with sophisticated line weight variation, careful value control through cross-hatching, and refined artistic execution. Overall style: classical hand-drawn caricature in black and white ink, refined cross-hatching technique, professional fine art execution, sophisticated subtle exaggeration, suitable for gallery display or fine art collection, approximately 8K resolution digital rendering of hand-drawn medium. FACIAL FEATURE PRESERVATION & EXAGGERATION APPROACH: Base structure: All features originate from reference photo, maintaining 100% recognizability Exaggeration philosophy: Subtle, artistic enhancement of distinguishing characteristics—refined emphasis rather than cartoonish distortion Eye treatment: Narrow slightly if natural narrowness present in reference; intensify gaze direction; maintain actual eye shape and spacing fundamentally; render with fine ink and cross-hatch; maintain eye color/tone from reference Eyebrow treatment: Emphasize furrow or arch as present in reference; slightly exaggerate slope or definition if characteristic; maintain actual position relative to eyes; render with precise ink work Nose treatment: Render actual nose shape with slightly enhanced definition; emphasize length if that is a feature of reference; add subtle angularity through cross-hatching; maintain proportion to face; respect natural bridge and tip structure Mouth treatment: Render natural expression with possible subtle exaggeration if characteristic (serious line, slight downturn if present); maintain actual lip shape and size fundamentally; convey through ink line quality and shadow work Jawline treatment: Render actual jaw structure with possible subtle elongation or emphasis if that is characteristic of reference; enhance definition through shadow cross-hatching; maintain proportion to face; emphasize existing angles Cheekbone treatment: Render actual cheekbone prominence; possibly subtle emphasis through shadow work if characteristic; maintain natural structure Chin treatment: Render actual chin shape and projection; apply subtle exaggeration only if that is distinguishing feature; maintain proportion Ear treatment: Render actual ear size and shape; possible subtle emphasis if ears are prominent feature of reference; maintain natural position and proportion; detailed ear rendering showing cartilage structure Face shape treatment: Maintain fundamental face shape from reference (oval, square, rectangular, etc.); subtle stylization acceptable but NOT distortion Expression treatment: Serious, dignified expression; subtle intensity conveying confidence and professionalism Overall principle: Start with 100% accurate representation of reference photo, then apply refined artistic caricature technique to emphasize distinguishing features slightly—the goal is a dignified, professional caricature that remains clearly identifiable as the specific individual, with subtle exaggeration enhancing rather than distorting character.
