She switched hands to hold the dagger. I'd think. She just isn't sure enough of the situation to put away or un-string the bow. One thing I don't see in modern illustrations is the bow case. From what I remember of ancient warfare illustrations, historical archers sometimes had a case that would hold a bow as well as arrows. I'd give her a hair band, if she's an archer, or a pony-tail. Hair in the eyes would be a problem. Of course, she shows the mandatory combat flesh to distract the enemy.
