i realize you were probably going for something wild, creative and abstact, but so much detail is lost with the way blown out whites that its really hard to tell how good of a digital photograph this is vs. your skills in post processing. Still a neat bit of work though. :)
Not sure of the technique you have used here, but looks like a neg art or solarise that you have adjusted saturation/hue. Like the effect, but think it is a pitty about all the lost detail on the bikes and in the white area.
