A while back, Toasty commissioned a long series of growth sketches from Cooner, and he graciously invited me to color some of the images from that series.
This is image #32 from that series, and the original line art from it can be viewed by clicking HERE (Note: Link leads off-site, to FA).
The other colored images from this series can be accessed through the following links:
