Hi Mike,
it's a good first attempt and I am assuming you shot this hand held because the EXIF says 1/4th sec shutter and ISO 3200. For any night shooting, you really will benefit with a good sturdy tripod. With a steady camera, you can bring the ISO back down to 100-200 and use a 30 sec shutter with a reasonable aperture and get a very nice shot.
I have shot from this exact location many times and find those foreground rocks to be too far with a wide-ish lens to contribute anything meaningful to the image. Schraubstock suggested shifting the foreground up and that is good, but i would recommend keeping those rocks dark because they really draw the eye and are totally out of focus.
I do like the white balance you selected as it shows a bit more variation on the city lights (blues, yellows, greens), which is nice.
watch out for the fearless raccoons that infest these rocks!

I agree with cropping it tighter to make the skyline more prominent. Here's an example, shot from the other end of the island, but close enough:
