Ambivalence

I'm just drawn to this image, and I think it won't take long to complete it. But I'm still unsure about what to do about the right side. I can either put the edge of the side wall in and sort of frame that side with it, or extend the back wall and the window behind the couple. But does that leave it feeling too open?
