Create a vibrant, colorful graffiti-inspired digital artwork featuring a stylized, smiling face. The face is an abstract representation of a smiling sun, rendered in a splatter art style. The sun's face is predominantly bright yellow, with shades of orange and red at the top, transitioning to shades of green and blue at the bottom, creating a smooth gradient effect. The face has two black, elongated eyes and a wide, black curved mouth, forming a cheerful, open smile. The background is a dynamic mix of bold, contrasting colors and abstract shapes, enhancing the energetic and playful vibe of the artwork. The splatter art style adds a sense of movement and spontaneity, making the piece feel alive and dynamic.
