Prompt
Close-up portrait of a single human face held in a 3:2 frame, the subject occupying roughly the lower two-thirds of the composition and positioned slightly left of center with generous negative space in the right third. The only light source is a cool phone screen held just below chin level, casting crisp cool-blue highlights across the nose, lips, and cheek planes and a faint warm fill on skin tones near the screen edge. Background is deep, featureless shadow that fills the upper third of the 3:2 frame and separates from the subject with a soft falloff rather than hard edge. Tight framing crops the temples and forehead so the eyes and mouth remain primary focal points, with subtle rim separation along the jawline. Texture details include visible skin pores, dampened matte skin sheen, fine lip texture, short facial hair stubble, and delicate catchlights in the eyes from the phone surface. Render as portrait-photography with low-key lighting, shallow depth so the face reads crisply against blurred shadow, and natural tonal gradation rather than artificial color shifts.
