A whimsical black panther silhouette in bright, bold moonlit colors, featuring a mix of traditional t-shirt art and 3D vector elements, with a focus on cute, quirky, and playful details on a dark, deep-space-inspired black background. Watercolor effect adds a soft, dreamy texture, while low-poly and digital painting techniques bring out the character's contours in a retro-style isometric bird's-eye view. The design would be rendered in stunning 4K resolution with photorealistic details, using Cinema 4D software, incorporating subtle shading effects and emphasizing the panther's front side stance with a slight turn to the viewer's right.
