I need help trying to figure out what else i could add to this image to make it not look so empty. Any suggestions would be appreciated.

Hmm… As it is, it’s really dark and hard to make out. Night time is kinda tough to depict, without it appearing dingy. Try adding in some blue lighting to bring up the ambient brightness a bit.

Well what you have is accurate for night time. Unfortunately, I think accurate is not what you want. Try what CMonson said about the lighting. Do you have a concept sketch you’re going from? That would help. The number one issue I see is the ground. Much too…flat.
