To be totally honest, Ascension, now that I can see the entire continent, I'm not digging it that much. I think the terrain looks way too messy, like the mountains and plains and forests are all jumbled together. I can't quite figure where one piece of topography starts and where it ends. I can't totally dig the concept of the look, though, and it does have the potential to look totally awesome, but I think you need to tone down the filters a fair bit, so that the oil painting look is more subtle and the map more "readable". But do keep working at it, it definitely has the potential.
Just my two cents, anyway.
