It looks quite good so far (the texture >< it is, well, annoying)
I've seen some things that would need to be fixed:
- The upper arms look too round, I think you should try to enhance it
- The chest looks a little big, well, when we look at the model overall, it looks weird because of the proportions legs-chest. That's my opinion.
- you should model half-closed hands, not a open one: it'll be easier to animate it without having the feeling that the hands are "wierd"
Remember, that's my opinion, feel free to do whatever you want
May we see the wireframes? especially to see the elbow joints.
