A good start!

All in all the map looks a little flat, though, especially in the green/meadow areas. You could try to liven it up a little by adding some trees, hills or adding some more variation to the texture. Try this map for some inspirations.

Another thing you might want to change is the mountains. Their placement now seems to be a little random. Try to form ridges instead of just plopping them onto the grey background.

Perhaps you could also try out a different font. It doesn't have to be something fancy, but the Sans Serif font used here looks very uninspiring.
