I feel the light needs to be lowered. The bed won’t fit on the wall across from the closet with the long window?

Colour-wise, the strong gold (which I love) needs to be repeated. That one is a Van Gogh from art.com.

Your end tables are great.

Lamps for side tables.

Thank you! Unfortunately the bed won’t fit on that wall. Very cool Van Gogh piece you suggested!

I don't think the execution in this example is great, but just to show you the concept. Pretend there is a matching window on the other side. I've read where people will mount a mirror behind sheerish draperies to reflect some light and make it look as if there could be a window there. Then hang the other draperies as shown, to match your other window on the adjacent wall.

Or totally cover the wall with draperies and have the window peek out from beneath some sheers:

trying this again as houzz just ate my previous post, so I'm doing it in 2 parts:

Or cover the whole wall in draperies with the window peeking out under sheers, I think this is a great disguise!

That may end up a lot of curtains in a narrow space. But I do think it's a great option. Instead of art I was wondering about an old window frame the same size/shape. Some are mirrored or used for pictures...to balance the existing window.

I like the drapery idea but a simple way to get started here would be to paint the trim the wall color and put a treatment like a shutter on the window painted the wall color.
