My only concern is with the first two characters. Its very important to me to understand how my characters move. It would appear that the way that you have designed your characters, they would not be able to move very well with their legs. I think that as a game designer I would like to use the characters you’ve created, however due to the limited mobility I would ask for a redesign of the lower extremities.
Sorry for the constructive criticism, I really didn’t see anyone else giving it.
Keep up the good work.
You should see the topology on some of his models. I have one from a commission and it is great! Very animateble. In fact it was made with animation in mind. I’m sure the topology on these guys is good for animation.
