Hi stevecim,

Could you post just the head result as a .3dm file ? (without the eyes and tooth) I'm curious about the patch continuity quality in pole area.
The result topology seems a little bit weird (some area seems very complex), but without knowing the original model is hard to tell.

Isn't the model supposed to be symmetric ? some area seems to have different patch arrangement.
