It looks quite nice, it has that old hand-drawn feeling.

A couple of comments though:

1. Maybe use a brush with less opacity and flow for the black & white mountain shadings.

2. Use a single round brush at different sizes for city symbols. Simple and good looking.

3. Work a little bit on your coastline. It looks a little "flat"...

And finally, just out of personal taste, I would change the texture of the map. But that's just me, I don't like that bumpy textures.
