Well, I've done a lot of pictures on the BMG Oekaki recently. Not to mention, it says how long each piccy took to draw, so I'll have that in parentheses...
Puu, Yusuke's spirit beast from Yu Yu Hakusho (55 minutes)
Miyuki, the character who flirts with everyone (30 minutes)
The 1337 Dunsparce God (60 minutes)
We Love Wobby! (48 minutes)
Kitsune the Vulpix and Kappy the Squirtle (66 minutes)
