Hey RPGMapMaker
I've just spent the past week searching for a cartographers software package, but didn't have much luck.
I had all ready decided that any close ups of important villages/towns were going to be created using ZBrush, however due to the poor results of my software search I decided I had no choice but to create my world maps with ZBrush. That was until I found your tutorial videos on youtube last night.

I have used Photoshop for years and even created my own brushes, however your videos opened some exciting new doors for me. THANK YOU!
It's strange how similar your workflow was to using ZBrush. It really blew me away.
Thanks again for sharing the time and hard work you obviously spent developing this technique. YOU ARE A STAR!!!
