Nice work
The forest difference is very subtle and I probably wouldn't have noticed if you hadn't mentioned it, but it works fine
I would leave the mountains colored as they are, it matches the map very nicely.
One thing I might suggest ... it seems like you have a slight dark glow on the ocean side of the coastlines. I'd put the dark glow on the land side, and a lighter glow on the ocean side for shallows. Nice ocean texture by the way
