Conventions are so much fun! The artwork I've been posting lately is for Anime Boston (which is this weekend). Especially with this con, fan art sells really well. I try to separate my original art and comics from the fan art stuff. It's rather depressing when I sell 80% more fan art than my original stuff. But that's what happens when you go to an anime con.
I'm going to be more comic conventions this year over the anime ones. Trying to break away from the fan art, but it's still fun to do. I try to make the pieces interesting, like making a calendar with this one or the 3D posters I posted.
I'd buy some of your original stuff if I was there. But, I would also have to remember to bring paper money which I forget to do quite a lot. A 3D calender would be a pretty cool combination. I've been making silly little custom pop up cards out of cardstock, vellum and other trinkets` I'd love to see you make one of those`
