Prompt:
Create a vintage-style science fiction comic book cover illustration. In the foreground, depict a terrified man and woman in retro-future space attire, reminiscent of 1960s design, facing left. The man, with medium skin tone, short, dark hair, and wide, fearful eyes, is seated, leaning forward, wearing a mustard-yellow spacesuit with black Nike boots and gloves, and a utility belt with pouches. He is wielding a ray gun with a prominent power dial on the side. The woman, slightly behind him to the right, appears shocked, with dark, shoulder-length hair, medium skin tone, and wearing a teal turtleneck top. Her mouth is open in a scream, and she's looking back towards an enormous green, scale-covered alien creature that is bursting in from the left side of the cover.
The creature has menacing yellow eyes, sharp teeth, a mouth agape, and a prominent fin running down its back, with an overall appearance resembling an amalgam of a dinosaur and a dragon. It is lunging toward the space-faring duo with an aggressive stance, implying an immediate threat.
In the background, depict an alien landscape with barren, red-orange rocky terrain and a dark sky that transitions into the blackness of space, sprinkled with distant stars.
