Thanks for all the tips folks. I took the P3 out on a semi-windy night aloft and shot this 1.5 second , ASA 100 exposure of the Austin skyline as it was getting dark. Totally agree that the best shots are while there is still some ambient light and not dark-dark yet. Then you massage the look of the shot with your EV dial for the proper affect. Pretty darn sharp.

In my opinion most of the images although they are nightshots are too dark. Especially the foreground. Most of the nightpictures I see on this forum getting much more interesting if you lightens/opens up the the shadow parts. Shoot in DNG it gives a much wider range of exposure editing and try to find a more pleasing balance.
As a example I did lighten up the shadows of your image.
