The sun is depicted mid-stride, with one leg extended forward, leaving a trail of yellow, curved stripes and sparkling star shapes. The background features a stylized, arched rainbow with thick bands of pink, yellow, and red, set against a clear blue sky. Fluffy, stylized white clouds are scattered around the scene. The foreground and sides are adorned with cheerful, stylized pink flowers with yellow centers and green leaves, reminiscent of 1970s aesthetic.
