Thanks for the advice, however (unless I did something wrong) I don't think it will work.
I did your method on the left side of the foot. I wasn't able to select the lathe line because it is vertical, so I just selected each of the CPs while holding Shift and then hit O. The right side is peaked, but notice the blockyness of it. I am wanting (an it may not be possible) to have the curvature of the left cup, with the flatness of the right bottom.

Well, I think I will just leave it bowed out. When in normal view you really can't tell.
I made the mouth a little smaller, so I think it looks much better now (look at the first pic of the post, reload the page if nessesary) However, I do have a few more cosmetic issues I want to deal with:
1: For some reason there is a seam right there, there is also one just like it on the bottom part of the visor (there is a shaded, spline copy of the visor below). There is a spline that runs thru these seems, but I don't know why that would be causing a visual effect.
2: This one I may be able to live with as is, but I would really like for these areas to be seamlessly smoth with the rest of the head. There is one of these on the other side too. They were created when I pulled the CPs back to make the roundedness for his mouth.
Thanks for all the help.
