The only problem I have is with the snow caps on some of the mountains. They look a little bit more like a shine effect, it makes the mountains look almost smooth and glass-like.
Yeah, I totally see what you are talking about. I think you're referring to those lower mountain ranges, which were actually the first mountains I worked on in this map. After I found my stride the snow caps began to look a little more natural, but it's definitely something I can improve upon.

I have to say, that naming scheme has me a bit all over the place - something dramatic must have happened to drop Cormyr to the north of Sembia
LOL I guess assuming people would not be familiar with the names was a little too much to hope for. I must admit, there is very little rhyme or reason for some of the naming conventions. Some of them were left of to the player for various reasons. I'm also not that familiar with the Forgotten Realms universe, so I just borrowed some of the names.

I appreciate the criticism, and hopefully in the future I will learn from some of my mistakes. I have to say, though, that I believed most people would criticize the map for the purple swamps. lol
