Great looking setup Sub'. That couch is nice man.
I'd move your LM1's up (I have the same ones and same color!).
As far as the moving curtain goes....hmmm...what's it gonna look like when it's all bunched up in its retracted mode? I dunno. I'd probably consider some curtains or blinds for the glass sliding door which is allowing the light spill before doing the curtain on a rail thing.
