Ringworld Covers

I know this next cover is a bit hard to see, but I really like it because it is one of the more accurate representations because it captures a bit of that no horizon feel as well as just how big the ringworld is.

 

This cover baffles me just a little. You have one of the most interesting concepts in science fiction and one that is very visual and instead you draw something that has no connection to the book at all. It is interesting, but I feel like I'm missing something.
