I can't figure out what is causing it, but there is something that is bothering me with the mountains. It looks as if the lower slopes (the non white ones) are rising higher than the upper slopes. I don't know if it is a layers problem, or if you have the contours set higher on the lower slopes.

Also, I am not to fond of the woodlands sinking into the ground rather than being raised up.

I do like the overall shape of the map, and I really like the way you did the shallower waters.
