Flash Portrait in Burgundy Sweater

Create a realistic close-up portrait of a young East Asian woman with medium chestnut brown hair loosely tied back in a low ponytail, soft messy face-framing strands, and natural understated makeup. She is wearing an oversized chunky knit sweater in deep burgundy, with a wide ribbed crew neck and textured wool stitches clearly visible. Pose her from the chest up, slightly angled toward the camera, head gently tilted, one hand raised beside her ear touching her hair, with a calm faint smile and direct relaxed eye contact. Use a plain warm gray concrete wall background with a hard on-camera flash look that casts a strong soft-edged shadow of her head and hand on the wall to the right. Lighting should feel like an intimate candid indoor snapshot: frontal flash, muted low-saturation colors, realistic skin texture preserved, visible T-zone reflection, fair neutral skin tone, crisp facial details, subtle pores, natural lip color, and no beauty-filter smoothing. Vertical 3:4 composition, upper body centered, slightly cropped at the sweater edges, photorealistic fashion portrait with a quiet casual mood.
