蓝色背景俯视鱼眼复古卡片机人像

Composition: strict vertical top-down overhead portrait, subject centered on a flat saturated blue surface, very close wide-angle/fisheye lens from directly above so the head and face dominate the upper half while shoulders, torso, legs, and small shoes recede toward the bottom; minimal headroom with black upside-down floor text near the top edge and small black text near the feet; keep the slightly awkward snapshot crop and exaggerated perspective.

Grade: early-2000s compact-camera flash look with saturated cobalt blue and bubblegum pink, medium contrast, crisp center sharpness with mild wide-lens edge softness, visible fine digital grain on the blue floor and faint skin texture with pores and slight cheek unevenness, glossy highlights rolling off a little harshly rather than softly, no beauty-filter smoothing.

Negative: beauty-filter smoothing, studio glamour lighting, normal eye-level perspective, long-lens compression, extra props or furniture, changed outfit colors, cleaned-up symmetrical crop, a different person or blended face replacing the uploaded Sidona identity, high-fashion model bone structure, elongated editorial face, or sharpened jaw, tiny, hidden, or turned-away face dodging identity verification, lightened blonde, silver, grey, or ash hair identity drift, plastic beauty-filter skin with no pores or texture
