The head and the hands are a niiiiiiiiiiiiiiiiiiiiiiice design. You could have worked it out a bit more though.
This set can become more epic if you apply some more realistic shading. It looks a bit random now.
I feel like theres a huge gap in workwise on the hands and head and the rest. They don't
look like one set, more like individual textures.
Perhaps thin the lines out a bit more, since they are really bold and black. And I think if you make the mouth on the hands a bit wider, it will look better.
7/10.
