Sometimes a drawing doesn't work the first time out. Developing a pose until you are satisfied and the darn thing looks right, takes patience and "eye". The one thing I really like about work in analog and digital, is being able to tweak a drawing digitally. In the days of old, making 5 or ten xerox copies to change size, redraw, was very painstaking. It worked but it took work. Tweaking an analog drawing can really help push the pose.
