You do have an indentation (or part of your wall is built out) in the picture next to the closet. If you knock out the drywall, (make sure there is nothing behind it) you could have narrow shelves built in. I've seen people do this to their bathrooms, when they lack linen space. So I hope I have described this so you understand what I am saying, not sure how to word it all. The small shelves could hold books, vases, pictures, momentos, etc. It would look nice if they were also of dark wood to match your bed. OR you could just center your tall chest and that would also look nice in the space. OR you could stain your huge mirror to match your bed and hang it in that area. And hang the small one (dark stain to match) on the back of your door. The dresser in the corner does look awkward. You need a chest of drawers (that matches your furniture) that is half that size. Also have you considered painting your bedroom a restful shade of green or blue? The yellow would be so bright for me.
