Wow, lovin it even nmore than I did before. The changes are all positives, far as I can tell. You still should do something about the hero and the first thin zombie.
The hero, especially, looks off balance. Probably mainly because, far as I can tell ,the back leg should be.. farther back, if you get what I mean. A complete pose revamp might not hurt (make him look more ready/design it with attack/idle/walk animations in mind maybe?), but at least balance him a bit.
The cop zombie, well... I can't really pinpoint anything, but somethign about it seems.. off... the hand's position is too stiff, or his body's too far leaning given the position of his legs, or.. something... Sorry this isn't much help, but... I dunno, maybe someone else can help me get the words out.
The car is totally sex. God, I love that car.
