Try flanking the FP with the two accent chairs and the sofa and the chair/footstool switched. Add some chocolate and blue drapery panels hung floor to ceiling over fiber roman shades at the window. I think the round table can go - it is a bit too tall for your pieces and too dense with your pastel palette. Something with glass and silver toned metal might look nice. Angle all of the chairs (plus footstool) and add a centering and grounding rug to the space. The two mirrors flanking the FP are not reflecting anything beautiful or interesting so I'd remove them. I don't care for the branch there, but would try it above the FP with art hung in place of the mirrors. Do you want a mantel? Have you looked for lamps? Check into an arc floor lamp to stand between the matched chair and sofa and to hang above your blue coffee table.
