i had tweeks perfect cell, it looked alright from the front, but from teh sides it was horrible, it deformed horrible, and it was still unskinned at that point, (it was sent to me to skinby whom i dont remember) anyways i forgot to save the model, as i did just view it with hlmv straight out of the aim window,
its very possible that that model is tweeks, show a front shot with no animations applied to it, i could tell you for sure then, then we all can get this issue dealt with properly,
btw 647 with that much done is not low poly in any form, at that point you shuld have 300 tops, even with modelling in details in the face
