A silhouette design of a black panther, with vibrant moonlight illuminating its form, creating a t-shirt art concept in 3D vector style. The panther is depicted in a cute and quirky manner, surrounded by bright, bold colors against a dark background. The piece exhibits a watercolor effect blended with digital painting techniques, featuring a low-poly structure with soft lighting from a bird's-eye view. Embracing an isometric style, it incorporates a retro aesthetic that is centered on the character. Rendered in 4K resolution with photorealistic quality, crafted using Cinema 4D, and presented from the front side, the design captures the intricate details and lively energy of the scene.
