I agree with Mark, the lights in the building give the picture balance and a bit more interest. I prefer the original without the dark frame though, I like the strength of the blue reflection and this has been half lost. I also like the stronger colours on the wheel itself in Mark's adjustment, makes it a stronger image altogether.
Nicely taken starting image and nice bit of post processing to bgring it to its stronger version. Good work all round
Cheers,
