Model Sheets outlines

I created both model sheets to get a better idea of what the two main characters would look like. 

this is deano's model sheet,  the main problem I see is with the second im on the left, the feet don't look right.

I like Julius' model sheet it had a decent amount of detail and accented edges in the right places.

I created both model sheets on photoshop using a wacom intuos 4, I think the outlines could have been a lot cleaner and sharper as the out line seemed to be slightly blurred. the muscle structure seemed to be fine with me although the hands could have been drawn out a lot better and the detail in the face could have been much more clear.
