Looks nice to me. Don't add anything. Give the eye a place to rest.

You've asked this before. ...........84 and don't add. Or.

The real answer if nothing is done ? The more extensive answer??? Go outside. Look at the roof line, and get 96 by whatever CENTERED on the obvious lift ...........flank with fixed glass at 84 It doesn't ALL need to slide.

You have inside/outside conflict, and we don't have dimensions or anything else.
