Gods, thats absolutely, completely amazing. Good work. I love the action, the expression, the horse, the angle... everything about it is great. Great watercolor.
The horse, her hair, facial expression, clothing, and the bow are all very well done. The pose is also very good. But I can't see where her bowstring is at the bottom of her bow. Is she stringing it while riding, or has she just let loose an arrow, or has she broken it?
... I wish I could paint like that...
Love it!
