Sketch Cards

After the March of Dimes sketchcards went up on eBay (see previous posts) I have had a couple of requests to do more. I did do a few sketchcards a while back just for the fun of it and it would seem like a good idea to keep doing them. No idea what people would like to see so I guess it will just be whatever occurs to me at the time. I guess its an opportunity to try out some random things that I have never had the opportunity to draw for publishers. I haven't worked for DC so a few DC characters might be interesting although I might try and work through every Marvel character I ever drew. Anyone know what they are? If anyone has any suggestion of what they think might be cool let me know. :-)
