Ok, so a bit later than I had hoped.. but here is the first update. I banged these out this AM. I also figured out a slightly better way to do this to reduce the amount of work, so these three mountains are different colors, but all use the same smudge overlay for the shadows and the same outline shape, with minimal changes. Two of the mountains (brown and grey) have a third lighter color on the Eastern slopes for a bit more variety.
End result is that after I made the smudge layer once, I just changed the underlying base color and made a few tweaks and I had a copy of the mountain with totally different color scheme.
EDIT: Running zip file has been added to the original post.
Oh... and please give me feedback, especially those that might use symbol based mapping programs. I don't want to spend a lot of time if no one will fine them useful. Also, if anyone wants, I can also create GIMP brushes out of these.
