I'm wondering about the dimensions in this room... It seems like it might be hard to fit a queen/king size bed from what the pictures show. Unless you have a twin or full, it might be too cluttered to fit everything? Ideally, you would not want anything to be against that heater. And how much are you willing to spend on time and money into this project?

With no constraints, I would suggest removing that carpet as you had originally said. Put in those dark laments. Repainting the ceiling and walls would make a huge difference.

Green and white wall = repaint white. Don't forget baseboards and ceiling either. You don't want to have different shades of white going on.

Blue wall = Accent wall. Use wallpaper or peel and stick decals. Possibly one similar to these? One, two, three. Amazon has quite a bit of options. You would want to give the room some texture. You already have the built in storage so you don't want to get too crazy by painting all of the walls different colors and drawing attention to every side of the room.

If you are strapped on space for space I could suggest something that would take a little bit of effort and vision. Which would be to remove those first 3-4 storage doors. So you have that L shape. Hallow it out, and put a desk in. Decorating inside of there would be another story haha.

I believe that could give you enough room for a nice reading chair to sit to the left of the heater, pointing at an angle facing the blue wall. Having only shelves on the right of the heater where you could put your books?

Not sure if that helped at all, but I would love to see whatever the outcome is!
