Retro Sci-Fi Hero Over Cityscape ラウンドシール

This is a stylized and colorful digital illustration with a retro science fiction aesthetic. A central figure, possibly a hero or astronaut, stands prominently in a vibrant, multi-layered landscape. The figure wears a brightly colored suit in shades of pink, blue, green, and yellow, along with a clear helmet. Behind the figure, a stylized cityscape with tall blue buildings is visible against a yellow and red horizon. Above, several blue flying saucers and parachutes float in a dark blue, star-dotted sky. The overall style is reminiscent of vintage sci-fi book covers or posters, with flat colors and bold shapes creating a dreamlike and slightly surreal atmosphere. The composition and elements suggest a narrative of space exploration, heroism, or a fantastical journey.
