foremost:

The planet/world distinction was just an oversight. As for the dark side of the planets, when I was making this I was imagining an interactive, far-future type map. So, while I made a static image, I was imagining that the "real" map has the planets rotating and exposing different bits of land as they go. Maybe I'll do a planet specific map later that shows the whole world unobstructed.

Ilanthar:

Thanks for the compliments. I had considered jazzing up the star but wasn't sure if that would conflict with the style of the smaller planets. Perhaps I'll try it out, see how it looks.
