I think there is some really good work in this piece but you need to give some attention to the pose and proportion of the left arm and the feet need to be reworked. Sorry if that sounds a little unkind but I wanted to be helpful . Looks like great work on the hair and face, to finish on a high.
I really like this sculpt, and it is a definite improvement on the last one you posted (although I liked that as well). The armour and tabard like garb look very well sculpted, as does the face, though I'd like to see a closer look. I assume you are adding a weapon in the free hand, as he is poised like he is defending with a sword/other weapon. I am very interested to see how you improve, and would like to see more of your work if you have any pictures... great job!
