I have had an issue with the "flat bottom mountain" This gives me some ideas. I like the "bit" of green too, that is a nice touch.

The lines in the newest one seem "off" in some way (not that we would get a close up if it was put on a map). The lines might be too "hard" or slightly out of alinement with the shadows... either way this is a cool mountain and I hope to make such things with my tablet soon.

Thanks for shareing. Reped!
