Looking at the original (starting) map, I kinda think it might be the combination of the outline around the continents + the bumpmapping of the ocean that makes it look kinda like its floating. And looking at the updated versions now, I think the first of the two looks much better than the second (and the original). I like what you did with the water.

I think the dark forest for jungle/light for temperate looks great. I'm a little iffy on the marsh - the blue looks odd, somehow. And the lava on the volcano, seems to bright in the lower-down parts, if that makes sense. Great map!
