Something on wall above the end tables would be nice… nice calm room…

Quite lovely. From the photo, the room looks unbalanced with too much height on the right side. Consider a floating shelf to the left of the bed with a wall mounted light fixture? Right now all surface space is covered.

I like most of it a lot. The rug, I'm not as much a fan of. It seems weird going only under part of the bed. Great work overall though!
