Hi Kelly,
Welcome aboard. I have come back to your photograph a couple of times since I first opened it last night. First of all, the composition, I think is very good. What I consider a relatively mundane roll of mountains is really brought alive by the moon. You also did a great job with placement of the road, which looks like you are going to drive right into that moon if you move far enough. Every time I look at the moon, I think it is going to land into the mountains. It is so large, it almost looks fake.
The exposure is very well done as well. It is very hard to get great detail in the moon unless you are photographing at exactly the right moment. Obviously, you did that. As to what to do differently? Honestly, I think you did a great job. If you are interested in some variation, it might be interesting to see some tighter versions of this - particularly of the moon coming up the mountain range.
Cheers and welcome,
James
