Is the best placement for the bed on that wall with the non-matching windows? If so, maybe drape the entire wall just to the top of the half round--will that allow the curtains to cover the outside edges of both windows?

Since the bed and night tables are dark, perhaps fabric similar to the wall color.

You have two issues, first is the mismatched windows. The second is that it doesn't look like you have enough clearance around the windows for properly sized hardware and curtains.

I would research inside mount shades or plantation shutters and put them on all the windows. You'll be able to find other ways to texture and softness to your room

So is there a way for you to place the bed on this wall? The other walls don't appear to work.
