green velvet sofa 3d model

"Design the backrest of an L-shaped corner sofa in ultra-realistic 3D, inspired by the provided reference image. The backrest should feature a smooth, continuous, asymmetrical curve with a fluid, sculptural silhouette. Upholster it in a soft sage-green fabric with a matte texture and absolutely minimal seams. Seamlessly integrate a hand-woven natural rattan panel on the outer side and back of the backrest, ensuring it blends organically with the fabric. The overall form should appear biomorphic and "grown," not manufactured, with soft, gentle edges. Ensure precise measurements and proportions are maintained throughout, making it suitable for a luxury modern interior. Render with soft, natural lighting, high detail, and warm tones, focusing on perfect geometry and realistic material representation from all angles."
