An interior designer for my bedroom

Im trying to make my master bedroom look put together, on a budget. I already have much of my furniture in the room, but am lookiny for advice on an accent wall and what to hang on the walls (for art and storage). Im not looking for anything fancy in terms of modeling and rendering, just some simple advice and ideas to guide me. I like a relatively simplistic look...but with some character. A few things to note, i dont have a closet, all clothing are in the dressers, red carpet and furniture must stay. Would love to add some decals or paint to dressers to help blend them in the room.
