Hello Virus- A

Welcome in showcase

I assume the map is for 3.1 because if no there is a lot of tileset correction needed..
You have also made the water entirely inaccessible, was that on putpose?
You have elevated the water highly in some places, it will look like sort of Tsunami sit.. if you wanted to make some waves, for sure there are not to be so high.
The hills on the ground have a very big difference between main terrain, it may cause units to climb it in unnatural way.
You can make the cliffs much better looking by using cliff brush on red tiles.. as the way you have painted it from textures tab is lets say inapropriate
Nice beginning Sir, but a lot to improve.
