Cinematic ultra-realistic 8K portrait of a young woman taking a mirror selfie indoors. She wears a cute yellow sweater with multiple red heart patterns and light blue denim jeans. Her hair is tied in a messy bun with a few soft strands framing her face. Soft natural lighting, clean minimal background, warm skin tones, subtle makeup, gentle smile, crisp mirror reflection, high-detail fabric texture, photorealistic atmosphere.
