Well, the thought was to have a brief session and finish the front part of the arm, as he drew free hand on the arm with sharpies and then outlined things and colored it in. After an hour and a half, he had finished the front, but for the ribbon and a couple of the details, and we decided to go on with the rest of the background (wind bars, clouds, shading, etc.) Next thing you know, it's been 4 hours, and I'm starting to wince and he finishes.
Hahaha had to finish with the upper most portion of my underarm....that smarted, but good.
here is some photos. I'll try and drag up photos from the beginning and do one long post with the progressive photos, once I am done with the arm piece.
