The bracer/arm guard on the left wrist would have the laces to the outside, not the inside as shown, so the string would slid on the smooth leather and not snag on the laces. If the arrow is loosed from the position shown she will definately hit her wrist as her elbow is locked and the wrist turned in, the arm should form a gentle curve away from the body and come back in at the bow, ie the elbow and wrist pointing out and the hand turned in slightly.
Also the flowing 'angel' sleeve would possible catch the bow string, especially if there is a breeze (the hair flowing backwards, and the clothes show there is a breeze) - an archer would have that tied out of the way or wear close fitting sleeves.
The fletches look good, but the cock feather should point away from the face, however thhis could just be a badly fletched arrow!
The fingers to the right hand look slightly in the wrong position (one finger over the arrow, two below) and they should not tough the arrow as this will effect the loose and make keeping the arrow from falling off the bow whilst drawing difficult.
Having said all of that I feel like I am being a real pedant, but you did ask.
The above comments do not take away from the fact that the picture is well executed and looks fabulous.
Please take the comments as observations of an archery coach and not as critism of a winderful picture.
it's nice to have a comment from a person who "know the ropes" all I must say that I exaggerated her a little, and after many hours that I've spent on her I didin't noticed that it's something wrong with her (I leave legs and arms 'cause now I'm to lasy to details like that) in this pic I will repair two things - "arm guard" (wow I don't know about what I was thinking while drawing it) and fingers that hold and arrow cause I'm an archer too and it was drew from photo of my
thank You for comment
