Any Ideas For My Outland AoS Terraining?

[BunnyAng]

Hello again hhivers, as the name says, i really want it to be outstanding. I've never really terrained an Outland tileset map before so I'll be happy to take any suggestions. I especially don't find the trees suitable (correct me if i'm wrong). So anyway, here's the map and if you feel you want something changed, feel free to state it out.

PS: The map is incomplete so don't expect it will function properly Still under bug fixing and heroes add-on.

Here's the map.
