Looking for a mapping Coach.

Hi guys!

I'll just get straight to the point. I am looking for someone that is willing to help me with several questions considering map making that I might run into while working with the editor.

Why? This is my first time working with the editor and since it's such an old engine the information that's available on the internet is very scarce. But don't worry it will be rarely any technical questions such as: 'I can't locate this file etc.' but more in the way of: 'What's the best way to create a realistic looking river? Help in structuring the lay out of a map that will be totally awesome,' and so on...

Current progress I made so far:
-Learned basic editing skills with the editor.
-Created a real-world gray scale map.
-Made it into a 4km with surrounding terrain map.
-Textured the entire map with Tpaint.

In process:
-Terraforming.
-Waterways. (Just made what it thought was a creek. Nope, 2 appartment buildings wide... So back to the drawing board.)
-Basic road layout.

Oh, and I know nothing about coding or anything, I'm just an engineering student :(.
