I would move the rug a few inches toward the window and about 2 feet toward the sectional so the rug edge is just underneath the front edges of the main part of the sectional. That will also give you a good walkway from your stairs at the other end of the room so you aren't walking on the edge of the rug (like in your last photo). The rug colors will be beautiful with your fabric. Post a photo when your furniture comes in.

I agree with calidesign, but if there is any way to move the sectional even a few inches away from the window wall, I would, so it doesn't look squished into the corner. That is one gorgeous rug!
