Hi Spleen....
Modeling is an art as well as painting and sculpture. And the secret of the arts is the harmony, the modeling must follow this rule.
Analyzing your model I can notice 2 big problems that are breaking the harmony
1- Lack of continuity in the splines.
2- A single control point as vertex for more than 4 patches.
I'm producing a video tutorial right now, using your model to demonstrate how to fix it.. I'll upload it tomorrow....
