Comfort when you play it is so important. I made a P-bass with a Pit Bull custom Jazz bass width neck and a paulownia body. I am very reluctant to change anything on it because when I play it, it's just "viceless." The body is comfortable. The neck feels great. The action is just right, controls are simple and easy. It almost feels like it disappears when I play it. So I am VERY reluctant to change anything on it. It may not be my most interesting looking creation, but it gets played more than any other.
Over time, I am guessing that you'll care less about the upper bout (which looks pretty good to me, BTW) as long as you just like the feel of it when you play.
