I think you've got the makings of a very nice map here. I like your coastlines, and the mountains are simple but very effective. I have to admit I'm not keen on your hills. Might just be personal taste, but they're a bit too blobby for me. I think they'd look much better if you flattened them slightly and extended the lines out a little at the edges. Otherwise, it's looking good, and I'd like to see an updated version.
