A whimsical and dynamic T-shirt design featuring a silhouette of a black panther basked in moonlight, rendered in a vibrant and bold 3D vector art style. The panther is portrayed in a cute and quirky manner, set against a stark black background with a soft watercolor effect. The image is created in a low-poly, isometric style, offering a bird's-eye view with retro aesthetic elements. This digital painting focuses intently on the panther character, illuminated with soft lighting, and offers a bright, colorful array that contrasts sharply with its surroundings. Achieved with photorealistic rendering in Cinema 4D, the piece is depicted from the front side in 4K resolution, with subtle creative modifications to enhance its playful charm.
