The first one is a bit on the blurry side. The second one I feel would benefit from a longer exposure for more light trails. I'm assuming you are using a tripod? All three are a little under exposed for my liking but its more prominent in the last picture.
I just checked out the exif info as well- I think you would benefit from a smaller aperture. maybe f/11 ish? lower iso, and then a longer exposure. I think maybe it would eliminate a lot of the noise in the image.
