Create a realistic vertical smartphone mirror selfie of an adult fantasy elf cosplayer sitting on a soft white sheet on a gray carpet in a minimal beige room. The subject is an elf princess cosplayer, wearing a delicate white draped fantasy outfit with gold chain details, thin arm jewelry, gold leg bands, and pale blue flower accessories. She has long silver-gray hair styled in twin ponytails, pointed elf ears, and a blue-and-white floral crown. Pose her seated with one knee bent close to the body and the other leg extended toward the mirror, creating strong foreground perspective with the bare sole and toes large in the lower left foreground; the other foot is visible near the bottom edge. She holds a light gray smartphone in front of her face, obscuring facial features, with her other hand touching her hair near the ear. Use soft natural window light, muted neutral tones, shallow casual indoor realism, visible mirror edge at the far left, baseboard along the back wall, and a slightly candid cosplay photography aesthetic. Keep the composition intimate but non-explicit, with realistic skin texture, fabric folds, carpet detail, and no added text or watermark.
