Lovely work on all those models! And the drool on that bug is......well, erm..... beautiful. I'd also suggest the Rogue Planet rules since pretty much anything goes and it looks as though your games would involve a lot of throwing people into conveniently dangerous scenery! Possibly Void Pirates and Starport Scum too, although I've only had a peek at those rules.
Great stuff and I'm looking forward to seeing more.
