Very nice image Jerry and welcome to CN's DSLR group!! You have a whole lot of potential here, and if you're like the rest of us you are re-processing this a few times... In PS watch your colors in the histogram and try to balance them, you have very red dominant here and could push the blue/green a bit. Another note is to watch your sky background as the night time sky is not completely black, and making it so you will lose faint nebulosity. So keep an eye on the histogram and always keep it from clipping to the left.
