Key instructions to preserve
No beautification, no face reshaping, no expression change unless stated.
GuardrailThe neon line-art portrait must be recognizably the subject despite the simplification.
IDENTITY LOCK: Use the uploaded photo as the sole identity reference. Preserve the subject's facial structure, skin tone, eye shape, hairstyle, and every distinguishing feature exactly — the person must remain instantly recognizable. No beautification, no face reshaping, no expression change unless stated. SCENE: A custom neon sign mounted on a raw brick wall replicating the subject's face in glowing neon tube line-art style — the sign is on and illuminating the surrounding brick with colored light. Below the portrait neon, a second neon element reads their name in a script font. PHYSICS & CRAFT: Neon tube glass — realistic glass tube thickness (12-15mm diameter), characteristic neon glow with soft colored light spilling onto the brick. The face is captured in a minimal but unmistakable line-art simplification using 3-4 colors of neon. Colored light falloff on the brick behind creates distinct pools where different colored tubes are close together. TECHNICAL EXECUTION: 35mm f/2.8, dark interior photography, neon as the primary light source, slight overexposure of the tubes themselves with realistic light bleed, background brick in warm shadow. HARD CONSTRAINTS: The neon line-art portrait must be recognizably the subject despite the simplification. Use only 3-4 neon colors. Do not add other branding or logos to the sign.
