The skymap might look bad with it, so you might want to use Deathstar's Galaxie skymap. Actually, I recommend that... looks much better with a night sky; the lighting was based on night time.
To add a bit of detail, I added some mapmodels to the dumpsters.. look inside them to find out what I mean.
However I did not edit the dumpster mapmodel itself, i literally mean look inside them.
Suggestions welcome
