8K Stylized Digital Portrait with Identity Lock - Nano Banana Pro AI Prompt for Profile / Avatar — AI 画像プロンプト

Create an 8k high-detail stylized digital portrait illustration of a person with a slightly happy, gently uplifted expression, maintaining realistic facial structure and natural imperfections, captured at an eye-level camera angle with the subject looking directly into the camera.
Use the uploaded image as the primary identity reference.
Face Accuracy (Critical)
Match the face with 100% identity accuracy. Preserve exact facial structure, bone anatomy, grooming details, jawline, cheekbones, and forehead proportions.
Subject & Expression:
The person has natural eyes with visible iris details. His face shows noticeable forehead lines. His expression feels subtly warm and introspective, with a faint, relaxed softness around the eyes and a very slight, natural hint of a smile — not exaggerated, just a mild uplift in mood while preserving realism.
Hair:
Natural-length, natural colour hair, slightly naturally messy, with textured strands highlighted in lighter colour tones to add depth and volume.
Outfit:
He wears a dark green and brown plaid (tartan) jacket with a loose, painterly pattern. Underneath is a muted beige/tan button-down shirt with a neatly tucked collar. The clothing should feel grounded, simple, and slightly worn.
Composition & Framing (IMPORTANT):
Head-and-shoulders portrait only (no full body)
Subject perfectly centered in the frame
Shoulders must NOT touch the edges — maintain clean breathing space
Bottom of the artwork should fade into a soft, rough, painterly edge (subtle cut-out feel)
Negative space below the portrait to draw focus upward to the face
Background:
Minimal cream background. Behind the head, place a bold orange square with slightly rough, painterly edges to create contrast and a halo-like framing effect.
Lighting:
Soft directional lighting from the upper left, creating gentle highlights on the forehead, nose bridge, and cheek, with subtle shadows on the opposite side to enhance facial structure and depth.
Style & Rendering:
Semi-realistic illustration blending editorial portrait art and graphic novel style
Strong sketch-like linework with expressive strokes
Visible textured brushwork and painterly shading
Dry brush effects, especially around the shoulders, where the image softly dissolves
Natural skin texture with varied tones (subtle reds, neutral hues, faint bluish undertones for stubble effect)
No beautification — preserve raw realism and imperfections
