Yen, I'd try one of these colors on the wall. That yellow is just way too bright and really doesn't match anything in the room.
Do you know what color sofa/rug you're going to buy?
Can you stand in the front door opening and take a picture from that angle?
here are some neutral colors that work w/almost everything, including your floor.
and remove those sagging drapery rods. (see how it bows in the middle?) the drapes are too heavy for the room. Get some lighter ones that hit the floor and raise the rod up higher.
do it like this pic
see how the rod is mounted at least 6-8" above the top of the window? do that, then measure down to the floor. that's how long your curtains need to be.
Or just do some inset blinds like they have on this window, or these:

Raising the rods and getting lighter curtains for a more elegant look. A+ idea! Also love the blinds
