Update

I won't keep posting pictures of my new developments as I'm sure that will get annoying fast (unless that is encouraged).

New development: I have transformed a continent map into a world. I have added stars as background, I have given the planet a glow around the rim, added a dark side of the planet, and lastly have given the illusion of city lights on that dark side.

The last one I'm most proud of because it is not just random noise, rather it is based on the geography of continents.
