Lookin good Edward. I like the political boundaries, countries on your map. What is the size of the region depicted? I will guess a medium size continent, in the Northern hemisphere, with the equater somewhere below the south edge. It does not appear to be a global, world map. So I think "earth like" and "blue marble" in the subject refers to the coloration, not the scale. I like your map's sea floors more than the other map shown!
