Create a high-quality, extremely detailed image of a vibrant graffiti-inspired digital artwork featuring a stylized, anthropomorphic block character rendered in a colorful, cartoonish manner. The block has a gradient body transitioning from green at the top to yellow in the middle and blue at the bottom, with exaggerated, rounded edges that give it a soft, friendly appearance. The character's face is highly expressive, with wide, black eyes, a bright pink nose, and an open mouth showing a large, happy smile. It is holding two small blocks in its hands, positioned in a boxing stance with thumbs up, giving a sense of victory or enthusiasm. The background is a dynamic, colorful urban scene with bold graffiti elements and vibrant textures, enhancing the playful and energetic vibe of the artwork.
