I think you've got some good stuff going on here. The ocean is sweet (I love me some dark brooding colors), the overall land color is good, the font colors in the ocean are perfect but it looks like the other fonts don't have the same gradient going on. As to the farmlands, you're on the right track it's just that the farms are too big, I think, but I'm not sure of the scale. By the way, what is the scale? The forests suggest small scale but the mtns suggest large scale. The mtns don't match the forests as the forests have a heavy shadow, the forests could also use some stray bits sticking out of the edges instead of being such a crisp edge (but that might be a result of the shadow) and the little clumps also help, use more of those. Forest shadow wouldn't even be seen unless you're doing a village scale. But, not to worry, we all struggle with mtns and forests. Overall, not too shabby.
