I like very much your work!
Simple but effective. In particular I love your use of textures and colors.

Here are two requests for you:
- can you send me your desert pattern (or brush?), the one from the first version?
- how did you manage to add that beautiful "wave effect" to your coastline? I'm sure it's pretty simple, but I'm just a newbie, so a brief explaination would be wonderful

Thanks!
