@John Kerns Forms look nicely 3D overall, but there's an issue on how the wrist is designed. The big concave plane that makes up the wrist joint is actually part of the Radius bone (the one that twists on top). Also, try to draw the elbow (Olecranon) a bit wider, flat and more like a hinge joint instead of a pivot. Here's Marshall drawing from the "answer videos" for you to compare (make sure to check out the other examples too in the video). Hope this helps!
