The subject is captured nicely with an interesting mix of shades from the reflection. The entering shadow line on the background, left of the string, is very slightly distracting to me relative to the string (just to nit-pick :).
I would bet good money that you are getting a DNMC vote or two, so good luck with that. It's a solid picture (and that surface is indeed reflective) so I hope you do well.
I like a lot this shot, it's clean and well composed, but I don't get a real connection with the challenge, sure the star does reflects a little but not enough to convey the idea of a reflection. I won't rate cause I don't want to rate low.
I like this... very symbolic and reflective on a couple of levels. I wonder if it might have even more impact with a strong background color ... but maybe that might be too cheesy? Either way, I like the composition too :-)
clever, more interesting bokeh in the background would make this more better for me - I'm guessing your creativity isn't being rewarded by the voters at large - sorry if that's the case. I appreciate the originality
