like the duotone idea. For me, everything feels too close to the borders. i think if you gave your composition some room to breath it would be quite pleasing. perhaps you had a limited background to work with
I've spent a couple minutes looking at this. I like the contrast between the two sides but it doesn't quite come together for me. The composition seems static and the tonality seems "off." I think I would prefer a little more contrast and a more subtle color toning.
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
