Thanks all for the constructive criticism.

This photo was shot at F11 with a long exposure. I did use a tripod when shooting, but I shot from a deck and without a remote so that may attribute to the blur, which I didn't notice so much before!

I did think of cropping out the cars, but I liked the way the color reflected on the cars, so decided to keep them in.

This was really one of my first attempts at shooting fireworks, so I will keep all your good suggestions in mind (especially the portrait shooting).

Thanks!!!
