Selfie Portrait with Cold/Warm Lighting Contrast

Prompt

【Subject】A young woman with dark brown-black hair tied into a bun, with a few wispy bangs falling across her forehead; she looks straight into the camera with a calm, slightly languid expression. Her right hand rests on her cheek, and her left hand holds a phone in a selfie pose.  【Makeup & Skin】Natural, translucent makeup with clean eye makeup, clearly defined lashes, and glossy lips; her skin is extremely delicate, and her overall complexion takes on a blue-violet sheen under the cool lighting.  【Clothing】A white thin-strap low-cut top (simple, fitted style).  【Accessories】Layered transparent pink bead bracelets and a gold delicate chain bracelet with a small flower/four-leaf clover pendant on her wrist; her nails are painted in a light nude color.  【Props】A bright yellow phone/phone case is very eye-catching (located in the lower-left corner of the frame), enhancing the realistic feel of a casual social selfie.  【Scene】A dim restaurant/bar atmosphere, with heavy black curtains as the background; wine glasses and small items are placed on a white round table, and multiple warm yellow table lamps create a cozy ambient light.  【Light & Color】The subject is illuminated by cool blue-violet fill light (such as screen light/LED fill light), while the background glows with warm yellow tungsten light, creating a sharp cool-warm contrast; the background is slightly blurred to highlight the portrait.  【Photography Language】A vertical close-up half-body shot (above the chest), with a slight top-down/eye-level angle, featuring the texture of a phone portrait mode, medium-to-shallow depth of field, and visual texture that is “clear yet soft.”
