How to Layout my bedroom?

I do think the space between my dresser and bed are slightly shorter in distance. I want to get a mirror and put it somewhere. I also have a walking pad but unsure where to place it on top of using it while doing work on my standing desk. Do I flip the desk around so it faces the wall? Do I move my bed and nightstand? I feel like I have a good space I just don’t know how to work with it, pls help
