Heya. Looks pretty good to me. The space is a little nebulae-heavy but that can certainly be explained I think. Another thing that caught my attention is that The Big Empty and Raider's Run sound sort of Firefly-ish, while the names of the systems are a little more "serious" so they don't, to me, match very well. Depending on what you're going for you might try naming a couple of the systems things like "Bob's Hope" or "We Made It" or something to match those...or rename those more seriously, something like "The Kodar Rift" or whatever (yeah, skip my two system names...the first is TOO corny and the second is ripped from Niven ). Hope any of that helps.
