Ah, the lengthy-motion-blur-caused-by-driving-at-night technique. It's a fun one. I'm guessing that this is one of several that you took during this particular outing and selected this one from them. The colors and lines are interesting, which shows that you've got a good eye for composition. The problem is that, at root, this is the sort of photograph that probably everyone takes at one time or another, and the more of them you see, the more you realize that they all look pretty much the same. Unfortunately, there is very little to meaningfully distinguish between most pictures of this sort of thing- they are all streaks and blobs of light with very little form.
Also, the challenge was about the out-of-focus elements of the background, and the whole image here is a blur. It doesn't actually meet the challenge well at all.
I looked at some of your profile photographs (what are those-herons?) and those looked good to me. You also have an excellent camera, so it seems like you're in generally good shape. Just keep taking pictures!
while you have a blurred background, you don;t really have an in focus subject for the background to highlight. for me this shot does not meet the challenge
