I tried posting the pose file I used for the first image I posted in this thread, but I think it's too big for the forum. I understand that there is supposed to be a straight line between the arrowhead and the archer's drawing elbow, otherwise, all manner of physiological problems result.

The attached image has graced the opening page of my web site since January.  It's the same girl, with the same bow and arrow, but a totally different pose. What makes this sort of thing particularly difficult is the fine tuning of the arrow relative to the bow and the draw string. It takes a lot of fiddling to line everything up. Patience is key.
