The original man (first man on left) with the big boots : FANTASTIC!
It has real character.
The new ones ... not so good. Take some of Treviourous good points, such as shading the chin, arm movement, and use four frames, but his straight leg straight arm animation looks boring. The hair line doesn't need to be changed, I have a big forehead like that.
Work on your animation, and put in those big shoes!
The helmet looks bad imo becuase it doesn't cover enough of the face (and so would be useless in battle). The body shape for the orc is alright, but you need to squeeze a face in there.
