Besides creating maps, I'm also drawing pictures of characters for my games. I know that this board is aimed at mapping, but maybe you're interested in stuff like this as well:

As you can see, this is drawn by hand and hasn't been reworked with digital tools. I might do this in the future...
This is only a section of the original drawing. The original is in A3, but I only own an A4 scanner. I even messed up the scan, as you can see...
The drawing shows a mummy-lord, that was one of the main villains in a recent campaign.
I really enjoyed drawing it.

I'll definitly rework some of my drawings when I'm more proficient using the GIMP. As you can see in this thread, I'm thinking about buying a graphic tablet to take my scribbling to a new level.
