Create a visually striking t-shirt design featuring extraterrestrials encased within a transparent glass capsule aboard a spacecraft. Draw inspiration from the surreal and ethereal illustrations of artist James Jean, known for his intricate and fantastical compositions. The scene should depict a futuristic spacecraft interior, sleek and metallic, with advanced technology visible in the background. Inside a prominently featured glass capsule, visualize otherworldly beings — humanoid or creature-like — floating weightlessly. Their forms should be alien yet graceful, with bioluminescent patterns or subtle translucency to emphasize their unearthly nature. Surround the capsule with soft ambient lighting to enhance the otherworldly atmosphere, reminiscent of the atmospheric artwork of Android Jones. The overall style should blend realism with a touch of surrealism, focusing on meticulous detailing and smooth, clean lines suitable for a vector graphic approach. Ensure the design contrasts effectively against a clean white background, optimizing it for silk screen printing on t-shirts and similar apparel items. This composition aims to captivate viewers with its blend of science fiction intrigue and artistic finesse.
