Four-Panel Cozy Gray Sweater Selfie Collage

Create a realistic 2x2 collage of four soft indoor selfie-style portraits of the same young woman with {argument name="hair color" default="long dark brown hair"}, sitting on a bed or sofa in a cozy minimalist bedroom. She wears an oversized gray cable-knit sweater slipped slightly off one shoulder over a gray pleated or flowy mini skirt, with bare legs visible and a delicate feminine style. Her face should be intentionally obscured by a soft square blur in every panel, while her pose, hair, clothing, and room remain sharp and natural. Use warm beige walls, white bedding, a light sofa cushion, sheer curtains, and subtle decor such as a vase of white flowers in the background. The four panels should show exactly 4 different selfie compositions: top left, an arm extended close to the camera with the sweater sleeve dominating the foreground while she rests one hand near her face; top right, seated with both knees raised, one hand near her chin, sweater falling off one shoulder; bottom left, seated sideways on a bed with one knee bent, hand covering part of the blurred face, white curtains and flowers behind her; bottom right, wider selfie with extended sleeve in the foreground, skirt spread over her lap, one hand touching her hair, legs angled to the side. Keep the color palette muted gray, cream, beige, and soft brown, with natural window light, shallow depth of field, smartphone selfie realism, gentle shadows, and no text or watermark.
