I hope this doesn't come across as advice sounding all I-know-it-all-skygod, but maybe you can benefit from my experience of almost killing myself!
Night flying away from lit up areas should be treated as IFR. Meaning, make sure you have some basic instrument skills and can turn, climb and descend and fly level with reference to instruments alone. I don't want to unduly scare you, but you can kill yourself in a heartbeat at night if you're not careful. Happens all the time.
The night I almost killed myself on a go around at Inykoern airport with zero visual references and surrounded by mountains. I wasn't instrument rated yet, but had started my training. And thank god I had, or I'm pretty sure I'd still be there as a smoking pile.
Another eye opener here in the west is a standard departure out over the pitch black Pacific from Santa Barbara. You're in total darkness immediately and only after your turn around towards coast do you get any visual references. Many people have flow into the sea on that one. Stalled, or dived in from a skidded turn, eager to get back around an pushed too much rudder.
Night flying is great and you should do it as much as you can, but just be careful and understand the challenges.
