Love the ink brush mountains. I wanted to do something similar once, but didn't really have enough control. What do you need help with?
I like the map. If I could offer some critique though: The coasts are really well done except fro where they pixelate or form moire patterns, those ought to be fixed. The rivers look good, but personally I would've started the strokes going from the sea towards the mountains so that they tapered as they neared their source. Also, I find the background texture a little too heavy for my taste. But keep working on it, with such a good start the finished product is bound to be great.
Edit: My mistake I thought this was in the WIP threads.
