I really like the overall. It's a beautiful piece of work
But don't you think the rider is looking a bit weird? I would really like the see what would it give if you would change the way he or she handle his spear, cause it feels a bit awkward. And also I wonder if you could give it a bit of mass, just so he doesn't look so skinny compared to his head.
Well do has you please and I would understand if you don't want to change it.
