Frazetta, those miniatures have been designed with GW proportions. The guy knows what he is talking about.
I am also studying a degree in Fine Art, in which part of it I have to specialise in understanding human proportions.
I agree that when you convert something into a miniature, you do have to change the proportions in order to make it look correct. Prodos have done this on a few occaisions, when necessary (i.e. the original Cybertronic Chasseurs had small looking heads originally).
Trust that the guys will make changes as required.
I agree Micmellon, I really like the new Max. I am massively surprised that Frazetta hasn't posted anything positive about the lack of design changes... Ahh well, it's impossible to please some people!!!
