The Master Replicas pattern is wrong. The factory stuffed up in China and made it smaller. What demention of the mouth do you have at the back of the mouth ? It should be 850mm going in the red area from side to side. Just checked my MR Kermit and it to is 850mm, but they went wrong with his body size.ive built a few to the master replica pattern, its just not kermit to me sorry.
I think ive got the head with my next design, i was pretty close last time and have yet to try the mods but i also want to try reduce the mouth a little as im sure ive got my scaling off ever so slightly.
from what ive found the head shape is one thing and the mouth plate size is a total other ball game in getting kermit correct
