Nano Banana – GBR Neon Portrait with Loose Sketch Lines (Image Editing)
Use the uploaded image as the only identity reference.
Identity lock – face, hair, gender (100% from photo)
Keep the exact same face and likeness from the reference photo, preserving 100% of real facial structure and proportions.
Maintain identical eye shape and distance, nose, lips and mouth shape, jawline, cheekbones, chin, ears, apparent age, skin tone family, and gender expression.
Do not beautify, de-age, or redesign the anatomy; all geometric fragmentation must still align precisely with the original face.
Preserve the same hairstyle family (length, silhouette, parting, texture), rebuilding it with geometric forms and sketch lines but not changing the cut.
Core style – GBR with extra loose linework
Create a cinematic GBR (Geometric Broken Realism) portrait with a futuristic neon aesthetic based on the uploaded image.
Construct the face from fragmented geometric brushstrokes, sharp polygonal shards, and layered abstract blocks, forming a broken-yet-harmonious facial structure that still matches the original features.
Emphasize facial features using bold color segmentation instead of outlines, while adding expressive fractured edges and dynamic overlapping forms.
Extra loose sketch lines over the drawing
Add many loose, gestural sketch lines on top of the finished geometric portrait: energetic strokes that follow contours, planes, and light flow.
Use thin, semi-transparent lines that sometimes overshoot edges, cross shapes, and float across the face and background, creating a scribbled, dynamic overlay.
Include rhythm lines and motion lines that suggest direction and energy around the head and shoulders, without hiding or distorting the facial identity.
Let some sketch marks remain rough, imperfect, and slightly messy, enhancing the unfinished artistic edge and experimental feeling.
Color, lighting, and depth
Keep the cinematic neon bi-color lighting: magenta, deep purple, electric blue, and subtle warm orange highlights across the geometric planes.
Maintain dramatic rim light, soft glow illumination, and volumetric light beams to carve the fragmented geometry and sketch lines, giving strong depth and a 3D presence.
Use high-contrast lighting with HDR-like dynamic range, soft cinematic shadows, and luminous color bleed to reinforce the futuristic editorial mood.
Texture and paint handling
Balance soft, painterly digital strokes with hard angular geometry and the added loose linework, keeping an ethereal yet bold presence.
Keep skin tones warm and natural—soft browns, beiges, muted neutrals—interwoven with neon reflections and sketch lines that wrap around the geometric planes.
Background, composition, and focus
Use a minimalist, atmospheric background shifting from off-white or pale beige into a darker, muted cinematic space with faint neon haze and scattered sketch lines.
Maintain clean negative space but allow some loose lines to drift into the background, echoing the geometry of the face and adding motion.
Preserve shallow depth of field: the central face geometry and key loose lines remain sharp, while outer shards and background lines appear softer or slightly blurred.
Overall artistic direction
Overall style: highly detailed contemporary digital art, expressive cinematic composition, cyberpunk-inspired color grading fused with editorial fine-art illustration, now with a visibly sketchy, experimental finish.
The result should feel like a finished GBR neon portrait that still shows the underdrawing and extra gesture lines, highlighting process, energy, and emotion.
Negative prompt – strictly avoid
Photorealistic skin, overly smooth skin, anime, cartoon, flat illustration, low detail, blurry, overexposed, flat colors, excessive realism, plastic look, AI artifacts.
Harsh black outlines, clean vector style, or perfectly clean edges that remove the loose sketchy feeling.
