“第一次接触”科幻主题 T 恤设计

A {argument name="theme" default="premium pop nerd culture t-shirt graphic"} isolated on full transparency with no background, centered in a square canvas, featuring a {argument name="hero object" default="bold 3D flying saucer"} as the hero object, designed with a sleek metallic chrome body, glowing cyan underside lights, and a luminous neon magenta beam projecting downward in a clean dramatic cone; beneath the UFO, a tiny silhouetted human figure looks upward in awe, kept simple and minimal for readability, while small floating stars and thin orbital ring fragments add just enough cosmic energy without clutter; the only text should be the {argument name="text title" default="large title “FIRST CONTACT”"} in a single bold futuristic display font, oversized, highly legible, and placed prominently below the UFO; no tiny text, no subtitles, no extra words, no scenery, no frame, no halo, no background elements, crisp sharp vector-clean edges, optimized for direct-to-garment printing and merch sales, high-resolution 4000x4000 px, professional 3D render quality, isolated on complete transparency, 1:1 square ratio.
