Office is the room labeled bedroom #3

How wide is the window well? This could be a potentially fun little niche. I love the black white and gold color selection. I think you could do several pops of color not just one color. Pic three colors you like and play around with different hues.
Wall opposite of closet would be a great focal wall for a bold graphic wallpaper. Lower shelving units on either side of the window well. Try putting desk out in the room not on a wall. Depending on size of desk would look great in front of focal wall. Cabinets could still be placed on focal wall. but i would keep them low ( no more than 42") this would allow you to do decorative accessories on top while still being able to see the focal wall. I would also try putting in an area rug for visual interest.

Studio Q - it is 33" wide by 90" deep from the window to the opening for the rest of the bedroom. There is an outlet below the window as well. Any thoughts on what to do with the space? I'd hate to leave it empty. Also, what do you think about fuchsia and aqua? Any recommendations for a third color. My living/dining/kitchen is purple, grey, and gold/yellow, my powder room is coral and my master bedroom/bathroom scheme is a calming blue/griege. Thanks!!
