Okay a bit more progress on this. I took JTK's advice and added a nebula, I'm using Captain Elgy's "Blue Cluster" background included in the CE background pack as a placeholder at the moment. I also added the second moon seen orbiting the gas giant in ENT: The Aenar. I also refined the gas giant's texture.
According to Memory Alpha, the writers of the before mentioned Enterprise episode made Andoria a moon to solve the Andor/Andoria issue (DS9 called it Andor, ENT called it Andoria, which apparently caused some confusion I guess). I've decided to honor that idea, the gas giant is named Andor in game. The second moon seen never had an official name, but when I was looking at the background info for Andoria at Memory Alpha, it mentioned a background drawing in DS9's "Far Beyond the Star's" called "Honey Moon on Andoras." With that in mind I decided to use that as the name for the second moon.
Here's an updated pic.
