Fun.

This is an interesting concept. I always likebright colors and it is hard to get them in most night photography. Here, I think the backgroundsort of sitracts from the composition. The three colored cricles would have made a great abstract if they had been done against a perfectly (or almost perfectly) black background IMHO. Also, this seems very grainy, especially evident in the red circle. This is one of those shots worth going out and doing again, because it is a good concept. But challenging enough that it might take a few times to nail it on the execution.
