Little girl portrait, cozy nocturnal mood

A photorealistic vertical portrait intended to feel intimate and candid: a little girl (around 6–8 years old, mixed ethnicity, round face, loose messy brown hair tied in an untidy ponytail with stray wisps) sitting at her laptop at night, her face and hands softly warmed by the monitor's amber glow, eyes focused gently on the screen, a calm, curious expression. Medium: realistic digital photograph with subtle film-like grain and shallow depth of field; the image is framed 9:16 portrait aspect ratio, tight mid-shot from chest to slight space above the head, camera slightly above eye level to create tender perspective, subject centered but shifted a little toward the lower third to leave negative space above for mood. Setting: a small, cozy bedroom at night with deep navy-blue window shadow and cool ambient moonlight seeping in; behind her, a small tabletop Christmas tree sits off-center in the background, bokeh of tiny warm white and soft multicolored lights and delicate ornaments creating a soft halo of color. Light and color: strong warm key from the monitor (amber #FFB86B) on her face and palms, contrasted by cool bluish room fill light (deep navy #0A2342) and muted pine-green accents from the tree (#0B5A2B), overall soft and low-key with gentle highlights on skin and hair, soft edge shadows on the neck and shoulders. Textures and props: matte laptop surface, a ceramic mug with faint steam on the desk to the side, a wool throw or cushion visible at shoulder level, wooden desk surface catching tiny warm reflections; ornaments are small glass and wood, slightly reflective. Composition notes: shallow focus on the girl's face with creamy bokeh on the tree lights, crisp texture on eyelashes and hair strands, soft falloff into shadow around the room, enough negative vertical space above for potential overlay but keep mood undisturbed; crop strictly within 9:16 portrait bounds.
