A 3D kawaii chibi-style character with a large head, expressive face, and small body, wearing a red and white striped t-shirt and blue shorts, in a waving pose with one hand raised, with a friendly and cheerful facial expression. The character has light skin tone, short brown hair, and wears a digital watch. The sticker has a thick white border around the character and includes a white speech bubble above the head containing the phrase: 'HELLO!' in bold black font. The background is transparent or solid dark teal for display contrast. Lighting is soft, with gentle shadows for a 3D pop-out effect. Style is playful, glossy, cartoon-like, ideal for mobile sticker use. The rendering should be clean, high-resolution, and emotionally expressive.
