Thanks Joe, I wanted to create a tutorial that shows both a hand drawn approach (I include smudging in this category) and an automated approach.

I like those mountains a lot. I'd perhaps say that the shadows near the ridgelines are a little extreme compared to the rest of the mountain - the shadows should stay dark for most of the width of the mountain before tailing off around the base. Also, the river bump mapping is really extreme - the banks of the rivers have a stronger shadow than the mountains! Great map though - and a lovely example of what can be done with texture and colour and then enhanced with a bit of light and shade.
