Ha, had there been the common "underrated" thread I would have given you a mention. I gave this an 8 and in the challenge it was the lowest rated picture I voted that high.
You saw my comment before, I liked the exposure and the fact that you captured some secondary reflections as well. Perhaps some thought it too busy. I liked it anyway...
I like the angle chosen and the distortion of the glass, although I feel that this would benefit from a little locan contrast enhancement to make it stand out a little more.
