Hmm you juked all his critique, yet I agree with pretty much all of it. Maybe you should reconsider what he's saying. I have a few critiques too:
I don't think interesting character design will come about by making a dude, then adding a bunch of knick-knacks to him, like medallions and torn jeans and stuff. I think a good character is going to be designed top down, with a concept in mind, and then the details made according to the concept. I guess you could make a cool character the other way, as long as the details you add aren't trifling.
You seem sure the pose is natural, but my first impression didn't agree. He looks rigid, unbalanced, and confusing in his stance. I think I understand the pose you're going for, but this doesn't give the impression that his legs are under him in a way that could support him. The right (OUR right) looks too far forward. I suppose it is a complicated pose though. Also his arms are in an odd position, I tried making that pose and I can't see why I'd ever put my arms like that, elbows splayed out and all.
Pillow-shading, mostly on the jeans.
