Your very monochromatic right now. You can keep that theme and just add texture and maybe a little bling with a white shag rug, pillows and glass tables. Maybe a thin console under the art. (it seems a little high). Or you can add a pop of color through rug, pillows, décor and a bolder piece of art.

kudos to you Carmen, for hiding your entertainment wires !

I love your modern furniture! You could really add any color as an accent, as you are starting with a blank slate. I could see orange as a possibility. Are an area rug and floor lamp also in the plans?

First, move the loveseat from in front of the windows to the wall under the painting. Let the light in!

Find a great rug and a coffee table. Curtains. You've only just started. Good start. Enjoy the hunt.
