ISOT = Island in the Sea of Time. It basically means things are moved from their original place in the time-space continuum into other places. So you could have Nazi Germany at it's peak constructively moved and placed properly over Brazil.
Over all it's exactly as I asked and I can't have asked for a better commission
If there were a small critique it would be that perhaps Canada could have had its modern flag b/c the maple leaf adds a more naturalistic look, and while I applause you for remembering what the true confederate flag looked like perhaps the battle flag/southern cross would have made a better artistic choice. Also, is that green in Mexico supposed to be the Aztecs
Like I said, overall these are minor points, and it is absolutely brilliant. Why, I might have to commission my other two ISOT maps after this amazing work! Oh, and I love that America is labeled Olympian rather than DC (I seriously regret bringing DC into the mix after all the harassment I got from the fanboys)
