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.
