A young woman stands with arms crossed and a serious expression, gazing down at the ground under the nighttime sky. Her physique is slender, with defined abs and prominent ribs. She wears an A-line skirt and a small crop top, accentuating her flat-chested form. Her short, messy black shiny hair adds a touch of elegance to her appearance. The scene is captured in ultra-realistic, concept art style with intricate details and sharp focus. The volumetric fog adds depth, and the HDR 8k resolution highlights every element. The ambiance is moody, with a depth of field reminiscent of an f/1.8, 85mm medium shot. This visually striking image captures the elegance and complexity of the moment.
