So, we're doing a thread-swap now to steal all thunder from
the "graphics"-thread, existing from minute one of this forum?
The stylistic approach here... well, hasn't got style, to be precise. The iconic abstraction is so vehemently overdone that, apart from the loosely brown hair and clothes, Marty McFly is really not recognisable. That simply wasn't the aim of this model. The eyebrows are just somewhere in his face (further from the eyes --> more female look, and MJF's eyebrows practically touch his upper lids from most perspectives), the characteristic slant of his eyelids is not even hinted at, and the actor's rather small mouth... well, that barn door of a cookie hole that model's presenting...
This means, I find the comparison rather unfair (good thing it's not in the "graphics" thread!

). On the one hand, there's a great, detailed model with a great emotional facial expression that could never be reproduced in the game; on the other, there's a cheap, 10-minute Marty model that does not take advantage of any of the possible caricature/ slight feature exaggeration techniques which could make a more abstracted figure loveable.
