Need Help

[Hoernchen]

Thanks in advance already, I totally suck at terrains and need help desperately. I made a strategic map called Historic Wars v0.90, in style of Civilization Wars and Tales of Kaltazar: Boreal Conflict. Now most people liked it, but every single one told me to improve my terrain.
So if anyone can help me, I'll mention you in the credits and you'll have my endless thanks. Just tell me if you want to help and I'll send you the unprotected map.

Thanks,

Here's the map (protected):
