It's always fun to try to get the reference material for a piece like this. My model, the son of our good friends was game to give me the look I wanted but it was impossible for him to hold the pose without falling over, so he did his best and I took the pose in pieces. I laid on the cement of the driveway to get the low angle I wanted and then had him pose the different parts he could hold, one at a time.
Head and torso with one arm, then the second arm and then the flailing legs. I pieced them all together digitally to arrive at the photo comp above which matched my sketch That is what I used to create the final drawing. Both drawings are graphite on bristol paper which I will now scan and use as the basis for the final Photoshop paintings. Stay tuned for the finished illustrations as soon as I get them done.
