Wow. The fact that you used paint makes this even more amazing than I originally thought. The way the brush, air or normal (for the lack of the correct name), catches certain points in the creation is very very good and eye catching. To be honest, I don't think too many people notice the category information which is bad because they miss out on what a committed artist can do with paint, or any material for that matter.
The position of the body and the flow from the back of the head to tip of the arrow is astonishing. I haven't seen too many pieces like this, position and paint, but the way you caught the light and made the shadows astounds me and I've seen good lighting, mostly from traditional works, but still, very good job.
