Overused:
Grass tufts with Doodad Brush.
wrong tufts in wrong areas.
Autoborder.
Too much wall-shifting for some buildings.
The mountains were badly structured.
To much ground shifting for one Area and bad usage of ground shifting.
The map is Squary too I'd assume.
2/10, I hope my constuctive critics will help you on your way on to becoming a better and improved mapper.
Never rush, and take your time
