I like the colours. I even like the darkness because it is still legible, but has a real sort of style to it for lack of a better word. You may have given the continents just lightly too much shadow for my tastes, they are in the border of floating off the oceans but not quite there, like they haven't made up their minds.

The scale you've given there seems to me to be truly immense, I don't know if this is intentional or not. Consider that driving Barcelona to Berlin is less than 2000 km. Or that LA to New York is less than 4500 km (driving) and you see what I mean. The span of land you have there is over 12000 km. Russia and Europe combined are smaller than that.
