I guess all monitors are different. Your new furniture looks brown to me. It is a lovely color.

I would find a rug with the colors you like. Do you have any art that you love? Art goes a long way in really making a rooms look pulled together.

I would also get lamps. Will you be hanging the mirror that is over the dresser?

A couple of other pics that show the room in its entirety would help!

The furniture, carpet and walls all come off beige/brown. The set does not look remotely gray. Lighting can go a long way to bring out the proper color of furniture but that might clash with the walls you currently have. Using daylight light bulbs or cool white 4000k and above would have shown the gray color better than the warm lights you have now. However if you do that, you have the walls to worry about. The floor to floor carpet can be remedied by placing a large rug in a pattern or color you love. 

For the walls, I'd suggest you paint, a cool tone color of your choice not necessarily gray. If you absolutely don't want to paint, you can change the light bulbs, add the large carpet and put decor/accessories that are all cold shades (think blues, purples, blacks, grays, white, greens) and that might "suffocate" the beige. Take a picture of the remaining 2-3 walls and possibilities for furniture, decor etc can be Suggested.

Thanks for the suggestions. I am thinking of adding a sail boat wall art with light blue and brown. Also maybe a gray ceramic lamp on the nightstand and a plant in the corner
