Most of it was simple parts, I think the thing I would do over was the sweep to form the piece that joins the top and bottom. It turned out OK because I was really try to get my points correct on the line but I should not have created a line with a center line on a piece that straddles centerline of the model. Doing that can lead to a crowning surface right at the center. I should have used grid snapping and layed down and then adjusted points with symmetry. It still came out OK but it bothers me.
