What software are you using?

I like the notion of mapping Pilgrim's Progress. I've seen a few maps, but most of them were story maps more than geographical, like this one:

You've got a pretty good start. There is a disparity between some elements which are blurry and others that are crisp. Also, you could probably refine the colors a bit. The green highlights in your forests drifts toward neon, and the flat areas are very red. I don't necessarily mind a vibrant palette, but this color combination is just a little shy of garish, in my opinion.
