Use the UPLOADED PHOTO as the ONLY identity reference. Apply a TOTAL IDENTITY LOCK and keep 100% of the person’s real features: same face shape, facial proportions, nose, mouth, lips, eyes, eyebrows, jawline and cheek volume; same hairstyle, hairline, hair texture and color; same gender expression, age and overall body type. Do NOT beautify, do NOT slim the face or body, do NOT change age, do NOT change hairstyle or hair color, do NOT add or remove makeup, and do NOT swap the face with another person. The character in the image must look exactly like the person in the uploaded photo, only translated into this illustration style.
Expressive hand-drawn illustration style: an ink sketch + technical blueprint fusion of the SAME person from the uploaded photo. Rough pencil linework with chaotic cross-hatching defines the facial structure, hair and clothing while maintaining clear likeness. Architectural drafting overlays, visible construction lines, measurement marks, circles, arrows and subtle grid lines intersect the figure, as if the portrait were part anatomical study, part technical schematic. Abstract baby blue geometric accents (triangles, rectangles, arrows, underlines) cut across the composition, emphasizing key planes of the face and important design lines. The color palette is very limited: beige or off-white textured paper background, black ink for linework and shading, and soft baby blue highlights for accents only. Vintage sketchbook aesthetic, raw artistic energy, imperfect organic strokes, mixed media editorial illustration, conceptual poster design with a gritty yet intellectual visual tone. High-contrast ink shading, heavy cross-hatching in shadow regions, textured paper grain clearly visible.
Lentes e enquadramento
Framing: portrait-style composition (close-up or half-body according to the reference), with the head and upper torso centered or slightly off-center, leaving space around for blueprint annotations, grids and baby-blue geometric accents.
“Camera” feel: orthographic / illustration-like view (no extreme perspective distortion), keeping the pose, head angle and proportions exactly as in the uploaded photo to preserve identity.
Iluminação e valor (tonalidade)
Lighting interpretation: simulate a single main light source using ink shading only, with stronger cross-hatching on the shadow side of the face and body and lighter, sparse lines on the lit side. No soft airbrush shadows; depth must come from line density and black–white contrast.
Tonal palette: beige paper as midtone, black ink as dark, and negative space as highlights; baby blue used sparingly for emphasis on certain contours, grid intersections or annotations. Overall high contrast between ink strokes and paper, preserving all key facial landmarks so the person remains instantly recognizable.
Prompt negativo (Nano Banana)
NEGATIVE PROMPT:
clean digital painting, smooth gradients, photorealism, glossy finish, soft airbrush shading, pastel rainbow colors, minimal linework, flat vector style, 3D render, CGI, low-poly look. No cartoon/anime style, no chibi or manga eyes, no cute or simplified proportions. No realistic full-color skin rendering; avoid smooth digital blending and skin pores. No plain technical CAD render with sterile lines; the drawing must feel hand-made, rough and expressive. No removal of grids, construction lines, cross-hatching or baby-blue accents; avoid ultra-clean, minimal poster style. Do not change the face shape, hair, gender or age relative to the uploaded reference; avoid face drift, identity change, beauty filters or body reshaping. No text, logos or watermarks unless manually added afterward in editing.
