really impressed with your shading. the first creature's hind legs, in the picture from the back, seems a little flat though, I cant see the muscles as well as you've shown them in the very first picture. Can tell you've been working on your hand studies, personally I like your pencil sketches better than the digi one. Another picture that I really like is the one of the boy (can just see his face), I think you've captured his emotion very well. On the picture of the man next to that with the bands around his face I really like the way you've shaded his torso. Nice stuff, keep pushing.
