How to paint my bedroom?

These are the photos I currently have from Zillow so they are older so apologies for that. The old owners converted the attic into a bedroom. The carpet is not like this anymore, it matches that gray you can sort of see on the landing and the ceilings I painted white so they also no longer look this way.

But how the heck should I paint this room? And the wall with the chairs in the first pic is actually a bathroom. It's a U-shape basically. Kind of an odd space and Idk how to go about painting it. Also working with a textured ceiling. I wondered if accent walls on the window walls would look good (the bigger windows are west and the tiny one is east facing). I'm just at a loss, I'm looking to make it kinda dark academia or adjacent to that look if that sort of helps. That last two pics are the paint I was planning on.
