Red Planet
I was commissioned to do an alien world map and pretty much all the details were up to me. Usually that's not the case, clients have quite a few specifications for maps, so cases like this one are interesting and let me flex my creative muscles a bit. One of the ideas I had was to draw two different species kinda battling it out on the scale of the entire planet, changing the environment as they go along. So that's what this map is: the species on the left live in huge shielded cities, and the species on the right mostly live underwater, preferring a more rustic approach, where they grow most of their buildings, weapons, etc.
