It's lookin good. Just a few tips, pay attention to small details and it will look much better... details such as "rune boots", the shield that's stuck to his hip, holding the bow by the string, the cyclops eyes, the dumbell bone and the shading changes direction. First the light source is coming from the left, as indicated on the mage. Then it's coming from the right as indicated on the other people. You've got some quite sophisticated shading and some very good line work and blending. Keep it up.
