I find it very talented for a first head.. I just think you need some more practice and techniques, maybe look some up on Google or ask somebody and they can give you some tips. But over all for a first head, I like it.
Not very bad for your first try. I don't really understand the cracks though,metal normally has scratches not cracks. I also like the way the eyes fit in but the way you used light and dark silver lets the head down abit.
