2x2网格拼贴，年轻女性表情

A 2x2 grid photo collage showing four different expressions of a young woman with long, messy black hair and fair skin. She is wearing a plain black t-shirt. Top-left: smiling warmly at the camera. Top-right: thoughtful pose with her hand resting on her chin. Bottom-left: side profile looking away, serious expression. Bottom-right: playful expression, scrunching her nose and shrugging her hands up. The photos are shot on a 35mm film camera with a direct flash, creating subtle shadows against a plain, muted beige wall background. A few blurry polaroid photos are pinned to the wall behind her. Low-key lighting, candid, realistic, 90s aesthetic, grainy texture. --ar 1:1 --v 6.0
