I really like her facial expression.

I'm undecided about the pose though. It seems to me that her body is too straight and front facing.  I haven't used a bow and arrow for many years (I used to be quite good :P ), but it seems to me that the body should be turned at the waist  a little  towards the direction of the target and the head and arms not so severely  perpendicular to the body. 

It's the whole "centre of balance" thing.  To me the pose is ok if it's a "posed" shot, but if you are striving for an "action" shot, the body alignment for balance and shooting seems off.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
