I wonder the same thing. If you still want drawings I'd enjoy doing some to be submitted.

A while ago I did a mafia game deck of cards on a discworld theme. Most of my drawings are ripped off (with permission) from Tealin - an animator who has drawn a load of discworld characters.

anyway - they can be seen here.

DISCWORLD MAFIA

I've got a few others, including my original interpretations but no scanner at the moment.
