"Create a high-resolution image of a ceramic ashtray shaped like a single Crocs shoe. The ashtray should feature realistic details, including the iconic perforations on top and textured sole. The shoe should be black with a glossy ceramic finish, giving it a sleek and modern look. One of the top holes should hold a cigarette, with a small trail of smoke rising from it. Place the ashtray on a clean, minimalist surface to emphasize its unique design and functionality."
