T-Shirt Tシャツ

A cute green alien stands cheerfully against a deep black background, flashing a friendly peace sign. Its oversized head, smooth round shape, and large glossy black eyes give it a playful, approachable personality. Subtle highlights and clean outlines create a polished cartoon look, while the simple pose and bright green color make the character feel lighthearted and fun. The overall illustration blends sci‑fi charm with adorable kawaii style.
