Great capture. The colours work well for me. My general observation is that there is nothing about this image to suggest a longish exposure. For me part of meeting the challenge is to produce an image that also looks like the brief, as well as technically taking a 2 sec exposure.
this is a great shot, but I a not sure it is demonstrating the sprit of the 2 second challenge...while it may have been a 2 second exposure, it might as well have been a 1/200 exposure if you know what I mean
