The cave mapping is very useful for me, seeing as how I suck at mapping them! XD
You've really have grown here since I've last talked to you. And I'm going to have to disagree with cooley and Buizel 9. This may be useful for beginners who understand how to use Advance Map. If the follow this, it could help them improve, with better shape, and everything. (Lets hope they don't make the same maps! XD).
Anyways, great tutorial, haefele~
