I'm looking for a critique of the following photo:

How does that picture look to you? I took this during our "Light up
Cincinnati" event. Exposure was 30 seconds @ f/11, Fuji Reala. The
picture is unedited, however I plan on editing out the truck on the
bottom left corner. Any composition changes you would make? Any
adjustments? I'm always looking to improve my skills; after 13 years
I'm still learning.

Thanks in advanced.
