How to decorate baby nursery which has a red feature wall?

Hi, I’m at a loss how I can do up a baby nursery for a baby boy which has a feature red wall, the red is like a light burgundy or crimson sort of red. The rest of the walls in the room are cream. I can’t repaint it which I’d love to do so stuck for ideas. I like wall murals & things but of course clouds & space stickers etc won’t go well on red. Appreciate any ideas. Thanks.
