Create a 3D abstract wallpaper with a modern, sleek design, inspired by the style of Windows 11 wallpapers. The main 3D form should have smooth, flowing curves with a dynamic, organic shape, and should be textured with a thick, woven fabric material. The form should primarily be in dark shades of gray, giving it a sophisticated and understated look, while leaving ample negative space to create a balanced composition. Add subtle, vivid lime-green accents (#C8E70C) to the woven texture, strategically highlighting the form and adding a touch of contrast and vibrancy against the dark gray tones. The background should feature a soft, light gray gradient, transitioning smoothly from a lighter to a slightly darker shade, enhancing the depth and contrast of the image. The 3D form should be positioned slightly off-center, with lighting that emphasizes the texture of the woven fabric, creating gentle shadows and highlights that enhance the tactile quality of the material. The overall style should be clean, modern, and visually striking, with a focus on the interplay between the dark gray tones and the vivid lime-green accents for a well-balanced and polished finish --ar 16:9
