Gaea Terrain Studies

Hello!
Just a quick view at my first attempts and learning courses in Gaea! So there's the Artic Glacier and the Mountain Lake course that I've learned while the "Erosion study" is a little test map to check out the erosion in this software. Gotta say, erosion is the base of any terrain, it is imperative that it looks as natural as possible and I can surely affirm that this software is very interesting for those.
As you can see, some of those are really exagerated and it's on purpose : I wanted to get to the extremes this software could offer me.
