I need advice for rearranging my room

I gave measurements but I don’t think it would really matter as all I really want to do is rearrange my room.

I feel there’s not a lot I can really do, these windows are gigantic and I have TWO. Also they have a sill so my desk doesn’t sit flush with the wall which is annoying.

Sorry my desk and bed are messy, I was cleaning my room today and I’m still sorting thru my stuff while my pillow cases are in the wash lol

Also the reason my rug is in that horrible position is because I was vacuuming it and it was easier to vacuum that way, I usually turn it to be parallel with the bed, so there’s that.
