Guitar modeling: carved top

Hello guys,

I'm modeling a guitar body in solidworks,  based on this reference: http://img694.imageshack.us/img694/6396/014se.jpg (yep i know this is a neck thru) but I can't model the carved top properly. I have tried using lofts and the result is ok for the bottom part, but completely wrong for the horns. Any suggestions? I have tried also the surface fill function with some control points but nothing works.

(i have searched the forums and haven't found a valid solution)
