A little while ago I found that real life and it's usually far too hectic schedule was often resulting in my getting less and less time with my sketchbook. As a result I challenged myself to put together 100 pieces of 'pin-up' (or close to it) drawings. The idea being that it would be a way to keep me motivated and to have an automatic fall-back if I can't think of anything else to draw.
At the time of writing this I've been at the series for a little longer than I thought I would but I'm still having fun with it. At the very least it's a good chart to see my artistic progess (or lack thereof).
