Today's prompt: in hyper-realistic 4k and the style of Michelangelo a picture of a green dragon with iridescent scales hovering above a space-marine with her helmet off. the background is an alien world with orange sky.

So, it missed that this was to have the helmet off and that the dragon should be hovering in flight, and that's not in the style of Michelangelo.
However, I'm pretty sure I read a pulp sci-fi book with that cover on.
