All of these characters were done by Liam F. of White Rock, BC.  He is also in one of my cartooning classes and this was drawn just before Halloween. He's got Jack-o-lanterns, a skeleton, and me dressed as a ghost for Halloween (see my glasses over the ghost sheet?) Liam also included his own character "Goofball" between the pumpkins and in the top right corner. Thanks for sharing this art, Liam!
