You've got some lovely texturing on the land but the mtns look plateaued in the fat parts. It looks like you used the new tut by Flawedspirit but I would recommend lowering the opacity on the white swashes to at least 50% before doing the lighting effects, maybe set the blend mode to soft light as well. Oh, and also make sure that you use an airbrush tip and not a soft round tip when putting those swashes in...the airbrush tips are mush more subtle around the edges while the soft rounds are more noticeable and the hard rounds are even more so. The color scheme looks pretty good too except for the ocean, with the gorgeous greens you might want something lighter in the ocean (it's also very pixellated, I'm assuming from over-enlarging a pattern overlay). All in all it's pretty good but let's get those mtns fixed before we tweak the ocean.
