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.
Well, it doesn't really remind me 'cept for the bow and arrows...Just like it could be a good candidate for a more mature take on the spyro story (which I wish they would do for more things than just spyro.)
Freaking. Awesome. I absolute /adore/ the pose and the muted colors look gorgeous. And the friggin' perspective on the arrow is INSANE!
Just one small thing I feel compelled to point out; looks like she's shooting a compound bow[it actually makes me think of the Hoyt Rambo uses ]? You've got the cables down, but it seems that she's missing the actual bowstring. The purpose of the cables are to transfer most of the bow's tension from the archer and into the bow itself.
If its just your own design then completely disregard the previous bit and just rotate the draw hand so the palm is upwards; while having the palm facing downwards looks cool to no end, its much harder to properly anchor and get the full strength out of your arms and therefore makes shooting a bow more difficult. Also, she should have three fingers on the string[you CAN get away with two, though], one above the point where the arrow knocks onto the string, and two below as this steadies the arrow on the string. And don't forget to give arrows their needed fletchings; as you'll get little to no accuracy with out them.
I think the spare use of colours points out the interesting aspects of the pose even more. I agree to the people before me - it is a very dynamic piece, but at the same time the square overall composition (not counting the tail) defines some clear limits. Therefore the picture is dynamic but not hectic.
