"A detailed 3D rendering of a nerd emoji with large black glasses, a wide toothy grin, and slightly raised eyebrows. The emoji has a smooth, glossy yellow surface with realistic reflections. The glasses should have thick black frames with a slight shine, and the lenses should be slightly transparent with a subtle reflection. The teeth should be well-defined and slightly oversized for a comical effect. The background should be a simple gradient, emphasizing the 3D depth of the emoji. The image should be in PNG format with a transparent background." emoji
