Thank you lothel. I'm not sure I can do a tutorial because I don't have much of a system - its just lots and lots of shading and recolouring and luck. I'm also quite surprised how well they turned out. It is my second set of maps using the GIMP, and I'm still learning how to use it since I started in December. I think the main thing is confidence: if I had seen these maps last november I would have assumed that I could never make anything like that. I'm not very artistic (I thought!) or particularly good at computers.

If you wanted and had the time, I would be happy to take you through the entire process from concept to completion of an encounter map using the GIMP in the WIP thread here: http://www.cartographersguild.com/sh...Encounter-Maps. Just download the GIMP (its free and works on mac or pc) and post in that thread and we'll work through it stage by stage together.
