The blocks of color reflected in the water are lovely. The composition doesn't quite work for some reason - I think it may be that the skyline is all essentially the same height, and thus feels a bit 'blocky'. 6.
There is nothing "wrong" with this picture...but It looks like a post card and nothing more. I would encourage you to branch out and use your skills to capture something unique! Think that an 8 is fair since the picture is good.
Austin, from Joe's crab shack ? I find night shots can sometimes be stronger at twilight on a clear night before the sky goes really black (or orange like in this case) The deep blue can really enhance the feel of the shot.
Looks like a boat went past your foreground too, giving the slightly odd water reflections.
