I really like how the eyes become the focal point of this image and how you draw attention on them by giving them more contrast and detail. The sense of movement in it is really good as well. I wonder what would've happened if the bow had been a darker, cold tone and the trees in the background lighter, maybe mixed with the color of the "sky" a bit? At the moment you can tell that she's firing an arrow from her pose but the bow itself doesn't seem to "pop forward" from the background.It's still really nice and I think you've done well with the sketchy style.
