Create a 3D Disney-Pixar style, 4K resolution avatar of a young Black man with medium brown skin. He has short curly hair and is wearing square glasses. The avatar is dressed in a black shirt, carrying a backpack, holding a smartphone in one hand, and wearing a smartwatch on his wrist. The expression on his face should convey a sense of gratitude, perhaps with a warm, genuine smile and slightly raised eyebrows to indicate appreciation. The avatar is designed for a static post thanking followers for reaching 100 followers. Convert to PNG without background
