Chuck,
It sounds like your current position is better than facing NE if it is going to put everything at your back. If you want to put it at NE, then consider placing it in the NW sector of the room if possible, so you'll be able to see both the dormer and the door (or at least the closet).
Failing that, I'd probably not touch your current position if you I were auditing in your case, except to tilt the desk to W2 instead of W3.
