I'd put a large mirror above the dresser (about 3/4 the dresser width). Then, artwork with a colored frame above the bed (I don't mind what you have there ... can you paint the frames?) Nothing on the other wall or in the corner. I'd add a large rug, and another accent color - maybe yellow? You could bring the accent in through the artwork, the rug, and additional pillows on the bed.

kulrn hit it. A nice, restful pale blue would be pretty on the walls.

I agree with other posters about putting some color on the wall with paint. If that is not an option then I would suggest hanging your pictures vertically on the blank wall close to the walls edge by foot of bed. It would brighten and add interest to hang a frameless large oval mirror over the headboard of bed. I would also hang a large canvas print vertically over the dresser. A slightly different presentation of bed linens.Turn down the top of the comforter exposing an aqua (same shade blue/turquoise as your lamps) fitted sheet with top sheet folded back as well. I would stack the sham coverd pillows on top of aqua pillow cased pillows. Lay a nubby white throw across the bottom of your bed.a couple straw stools or narrow bench at the foot of your bed would add texture and function. Just a few ideas you might try. Good luck.

Is this your master or a guest room or your daughters room? A bit more info would be helpful

I would 1st center the bed and night stands to the wall it’s on.

I would definitely paint the walls a beautiful, dusty blue.
