A 3D vector art design of a black panther silhouette under moonlight, featuring cute and quirky elements. The t-shirt art incorporates a bright, bold, and colorful palette against a black background with a watercolor effect. Using digital painting techniques, the low-poly panther is depicted with soft lighting from a bird's-eye view in an isometric style. The design exudes a retro aesthetic, focusing prominently on the panther character. Rendered in 4K resolution for a photorealistic effect using Cinema 4D, the front side composition creatively blends the essence of a mystical night scene with a touch of modern art.
