I recommend md-canvas for well-priced contemporary canvas art. Looks great and a lot of bang for the buck. You can do a long piece horizontal over your bed for example.

I am not loving the location of your dresser. I was going to suggest swapping the desk and dresser, but I see you have a vent on that wall. what is the function of the desk. is it a vanity or a desk. if vanity hang a mirror above, if desk hand art. I agree with adding the burgundy around as an accent

Your bed needs to be centered on that wall. And remove that burgundy chair, that matches with nothing and it would make no sense to start buying burgundy accessories just to try and make it make sense. And then you need everything ... night stands, a long dresser, an area rug, a bench for the foot of the bed, upgraded bedding, art, on and on. You need everything so if decorating is not your thing, which I'm seeing it's not, then please get someone with some decorating sense to help you BEFORE you start spending money. That is my best advice to you.

It looks like you need some window treatments, artwork, to change out the current light on the ceiling, and add some artwork. Here are a few designs of ours that might help with some ideas for you:
