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
