Thanks for the tutorial Ra-Tiel. Hopefully, if anyone else tries Paint.Net, at least your tut will give them a good start.

One thing I would suggest (is PDN supports it) is to try to soften the hard lines at the edges of your mountains. One thing I can think of is to create one or more gradients with the underlying grass on the outside and the mountain color on the inside. Then add your mountain layer colors on top for a more seamless transition with no lines. I expect PDN can do this, so give that a try.

Also, in case you did not know, you can attach images directly inline. You can post up to 4 mg or so jpg images and of course, the higher the resolution, the better....

Have some rep...
