it's a bit out of proportion in how it's foreshortened. it needed to be just a little longer and the forearm and fist a little larger in order to make it appear that it's outstretched. there's also a tangent issue along her chest line and the sword. they both meet on the same plane. when that happens you can't tell if something is in front or behind the figure.
Thanks for your reply. I hope it is not too much of an imposition but I have to ask a follow up question or two. How would an artist lay out the proper proportion for such an extremely foreshortened form? Would it be typical resort to cylinders and cubes receding to vanishing point behind the shoulder or is there another method? Thank you in advance for your patience with me and these pestering questions.
if you can, you should pick up books by andrew loomis. they are reprinting his books, and one that really goes into perspective is "successful Drawing" check out his other books at barnes and nobles. really nice additions to an artists reference library.
