Zeta Kai, that is definitely a beautiful map, and it seems like I can see craters along the shore of the land and the ice. However, the challenge idea states - regional as opposed to world map, as it would be difficult to show what is destroyed as far as civilization goes. Meaning, it would be nice to see roads that ended, half cities with the remaining in rubble, evidence of fallen civilizations. This map suggests destruction, only its difficult to see how it has affected the population.
At orbital height, one has to guess how much damage or affect the catastrophe has caused. It would be better I think to zoom a bit closer to the ground to really show the evidence.
