This is another one that I did for my own game world. It is three pages joined together, and the join worked much nicer here! I have then brought it into Photoshop and colored it. This one I am fairly happy with, but it is still not perfect. One thing that is happening, is I draw the ridgelines much like the Peter Fenlon maps, but I try to draw them in a light brown, but they don't scan very well, so I have to spend hours going back into Photoshop to draw them in.
I am thinking about doing the whole thing in pencil, then scanning, and trying to separate everything into layers to make them easier to work on, but that is quite a job also!
