Lovely tones of blue here, nice use of the moon for drama and illumination (to an extent anyway). Like that you did very basic editing, that's my fave too :-) I wonder about the high ISO, after all the wall did well for stability. I would've gone down pretty low in ISO, closed down the aperture and left the shutter open a lot longer.
The comp does look busy, you could almost split this horizontally into two separate shots. The sets of boats battle it out for your eye. Almost a little glare off of the sodium lights.
Overall, not a bad shot, just needs a little more work. Go forth and shoot!
I think that this might have been better if you cut out the bottom third of the picture. With the two rows of boats it leads the eye to two places instead of one.
Technically good with nice details captured all round. Just a little bland as an overall picture as none of the elements really captured my attention. 6
