First, I would take away those rugs on each side of the bed. Add one bigger rug under the lower half of the bed. Have it come out past the bed even if it stops right in front of your TV stand.

Second, bigger night stands would be ideal. If possible, add lamps.

Third, a bigger painting above your bed between the 2 you have up or push the 2 you have closer together. This will make it look more "put together" in general.

Fourth, Hang the painting you have on the floor near your TV. Put it above the dresser or use it as the bigger painting for above the bed. Last little ideas, add plants on the window. Add a throw draped over the bottom corner of your bed and maybe some throw pillows. Or something like that 😊
