Replace “nose, soft shaded nostrils, and lips with the chin filling the frame” with “extreme close-up centered on the lips, with only the lower nose and a small portion of the chin visible.” Strengthen “gentle highlight on the cupid’s bow” to “bright, controlled highlight across the cupid’s bow and lower-lip center,” while keeping “slightly parted” for the defined mouth shape.

Replace “clean studio lighting with a soft key light and delicate shadow falloff” with “single directional side light with pronounced shadow falloff and subtle chiaroscuro.” Change “minimal studio background with no discernible environment” to “deep matte brown background fading into black,” and replace “faint natural sheen” with “restrained glossy highlights” to keep the lips realistic without making the image feel brightly commercial.

Keep the fixed structure “photorealistic beauty portrait close-up,” “natural skin texture and pores,” and “shallow depth of field with the background fully smoothed out.” For each variation, swap “warm nude-peach tone” for controlled palette choices such as “muted rose,” “terracotta,” or “cool mauve,” and replace “soft key light” with “cool window light,” “warm diffused beauty light,” or “soft overhead light” to create distinct but consistent portraits.
