I would suggest painting the wall an accent colour and then putting some shelving over the bed, centering the bed on the wall, and having matching end tables each side. You could replace that lamp with a table top lamp. This will give you more balance, and make your room feel bigger and more well used. Something like the picture below. That room is 11' wide

HI -- Not sure I believe this one ?? So here goes..... center the bed , then lower the pictures and add a side table on each side . There you go ... no empty corner !!

Other than the advice above, clear everything off the top of the bed. Find a small green pillow or two for the head of the bed so that the color of the wall will have a relationship with something in the room.

Agree with lefty47 and then edit the top of the headboard after you do the above.

Looks like Ingrid and I see the same things!

It is about that time of year for Ingrid isn't it !???

Please lower the art over bed. Good Luck with your room!

I would have nothing on the right side of the bed (as you're facing the bed) and use a larger nightstand on the left side to fill more of the space you have there. What you have on the right side currently appears to be too small for the the left side. I'd then eliminate the floor lamp and use a table lamp on the larger nightstand. AND I agree with all those who suggested lowering the art above the bed.
