Post some photos of your actual room. I hope you will have a better lighting plan. It's impossible to see what color that actually is. The windows should have just the blinds, or blinds with floor length drapes.

The room is dark and basic. I like the art wall. The closet "office" presumes you have other storage for clothes etc. The lamps at bedside look contrived and naff. I'd prefer something more sleek. The curtain bugs me. I'd rather a tailored blind over that truncated bit of fabric. I'm also not a fan of those orphan high lonesome shelves. But......... À chacun son goût

You asked for opinions. It looks like a teen bedroom.

Looks like a dark greige paint color. Wall "photos" look to be posters of games in sepia or black and white.

It is gray paint.I lightened pic.
