Speed Painting and a Tank

A while back I joined a cool art blog devoted to speed painting. It's very challenging for me. The rules are: no use of the eyedropper, and you have to stop after 30 min. It's great practice. I'd like to thank Heather for letting me join her cool blog. These are mostly from cartoon backgrounds done in the 30 minutes.

And on a different subject, here is a tank. I'm sick of it for now, so I will post it.
