I'm not sure if its the zoom that was used to get the shot or the contrast but it is blown out either way. An interesting take on this challenge but the photo lacks clarity. Might I suggest using a tripod when zooming in so much. It may also be a cropping and resizing issue if you weren't zoomed in. Good luck with this challenge.
Interesting shot and composition. Your colors don't seem quite right, but that may just be me, having not seen the actual subject. Your border is mildly distracting and detracts somewhat from the overall effect...

One of the very best of the "detail" shots, a "readable" image that's quite compelling. The border's not doing you any favors IMO, though. Strong score from me.
