After our post on BlueSky’s collaborative art challenge blog, reader Aaron Zenz wrote in to share some other sites with similar themed drawing activities:

This Princess Leia was created by Dave McClellan and was found at the Avalanche Software Art Blog, which has also just started its Halloween theme, Ghoulsmire Castle.

Drawer Geeks already has dozens of completed themes, many of which ask the artists for their take on specific characters. The most recent is the Grim Reaper, and the results are fantastic. This Nosferatu by Michael Moore was from last Halloween’s Movie Monsters challenge.

Finally, Toon Club doesn’t seem as active as the other two, but it still lots of fun. This wonderfully-skilled cartoon gator is courtesy of user Yendorb.
