OK... but the wire wont be lower as it is fixed now. The wire in the pics below is the wall facing each other. They were leveled on equal height but the beam on one wall makes it seem a little above. But i think you guys are absolutely right that up and down lights wont look good there. I think you are right about down lights lessismoore. Would it look good if i go with two different lights on opposite walls??? it would look odd right.

I don't think 6 sconces are too many and your placement looks fine if that's your final furniture arrangement, but I wouldn't put them in yet. I love sconces, but they can make future furniture arranging more complicated. I'd put them in after your furnishings are picked and arranged so you aren't stuck looking for pieces that work with your sconce placement. Also, it might look overdone if your chandelier and the sconces are too matchy-matchy.

This will help get some light into the middle of your space. http://www.westelm.com/m/products/overarching-floor-lamp-antique-bronze-w890/?pkey=cfloor-lamps You could also do end tables or a console behind the couch and place table lamps on either. It doesn't look like you have any seating near the edge of your space and your existing lighting seems to be positioned at the edges of the room. So I'm not sure if sconces would help much.

I love your wall color. A green print bed spread with yellow and purple colors would look great with your wall. Can you move the mirror/night stand to another wall. It looks crowded in that corner. Then mirror glass side tables with drawers would really sparkle against the purple wall. And then art on the walls.This is not a bedroom but you can see how green, yellow and purple go together.
