These are rather nice, Dromedary.
I also love making maps, but mine are usually rather unsatisfactory. I prefer drawing with pencil and just lately returned to this hobby of mine (making fantasy lands not only inside my head, but actually drawn on map), but I'll gladly collaborate in my spare time.
One question: would you be interested in making an area map? I am going to run a manor-centric game, but would like to have the estate mapped. Historic look is something I would go for, if I had the time and skill...
