Anthony, it's indeed a nice shot especially with the railway nicely leading the eye from the bottom to the middle of the image to the main point of interest however I think it's a little too dark (even for a nightshot
). Apart from the small part of the terminal with the 2 airplanes you don't really see much of the airport.
Try to brighten it up a tad and I think you should be fine.
What I also noticed is that you apparently chose a short exposure time; that's really sad since if you increase the exposure time your image will become much more lively; see Serge's beautiful shot of the LAX

For such a shot I'd recommend setting ISO to 100-200, aperture to f9-f16 and let the camera and a sturdy tripod do the rest.
