Ok, I can hear the experts " you've got distortion on your map"...., that's correct, but I think it's pretty limitated and I will tweak this.
All rigging is done but FaceRig for shapekeys... I also havn't done muscle rigg for advanced deformations.... I'm so happy with the result by now.
... Also, I havn't applied all correction to the jaw movement but from now it allows extrem yet "realistic" deformation
Think I can complete the weight painting till wednesday... Hoooo... I love it taking alive....
