Soliciting advice..

I've finally finished painting my bedroom and attached office. The main rooms are a light greenish color, with single accent walls in a rich chocolate brown.



The hunt is on for window treatments, french doors, and more wall art, but I'm perplexed. I like nice clean lines, nothing too obnoxious. So, what would you do in this room with window treatments, throw pillows on the bed/chair, etc.?

We just picked up the picture we had framed, yesterday (which is on the wall above the chair, but blurred in the room photo). It's a fingerpainted mess that Kenzie & I did last year. It's really cool in person and we're really pleased with it. BTW, everything is larger than it appears in these photos. The room is large, the bed is large, the armoire is large. It all looks a bit miniature in these pics. Not to mention the colors aren't quite right, but I'm disinterested in trying to photograph it again.



Finally, I'm not opposed to recovering the bench. We bought the comforter because it had all the colors of the bench...but the bench is missing the orange color, and it looks "ok" but not quite right. So, perhaps that's the problem piece that needs to be overhauled along with the addition of the other elements???

I enjoy the styles of so many other bloggers, and am hoping that someone might send me in a direction that will pull this room altogether. I'm almost wondering if solid window panels and throw pillows is the way to keep it serene. But, what color? Or, if there is a fabulous print out there that will blend well, I'm all for it.
Any wise ideas?
