Short brown hair, big expressive blue eyes, warm friendly smile. He is wearing a yellow t-shirt and a small blue wizard hat with a tiny star on it. He holds a small golden wand in one hand. Background is a soft gradient of blue and purple with tiny sparkles. High-quality 3D render, Pixar style, hyper-realistic textures, 8k resolution, centered composition. The image must look friendly, safe, and magical. No text.
