We need to see the whole space to help you pull it together. The TV is too high and the stand is not wide enough for it. Peach is not working too well. The fuzzy rug and throw feel a little too much like bath decor. You could lighten up with sheers in place of the trellis patterned curtains.

The problem is the couch and curtains clash and it's really noticeable because they're right next to each other. I'd do a google search for rooms with green couches before you make any decisions to change anything.

I wonder whether the green and teal against the pale grey (or cool white) wall make the room feel quite cold. Have you thought about painting the walls a warmer color?

Jan hit the nail on the head!

I agree .

I am not a pro, so this is just my opinion. The room does not need much. Bring in a small round gold metallic table, the lamp does look a bit small now, but changing out the table may change that with out having to replace the lamp.
The rug looks cozy, but from the view shown it does not differ in texture from the throw and seems off. A slightly larger rug in vibrant hues would be lovely. If you prefer a softer look, a black and white rug would work well.

well that was strange, I posted this yesterday and it just showed up. Anyhow, I think you got some amazing suggestions from the others
