I was bored playing default maps, so I decided to make something new. I didn't knew earlier that site like this one exists :P. I'm putting my first map under your criticism.
(The original title is in polish)
I hope you like it :-)
The grass doesn't blend into the map. The pass from grass to desert must be done step by step, not directly. Here you just placed fat grass on normal ground. At the edges of the present grass, try adding less dense grass so that it will have a smooth appearence.
