"On the Rocks" does meet the Square Crop challenge. I think the subject itself is very different and also has a different perspective then most people would choose, which I think is a great quality to have. Unfortunately I think a lot time voters and people in general automatically have idea of what they would do and that is what they want to see.
The image itself is very interesting and has to make you stop and look. I am very glad you choose black and white, it allows us to see the frozen ice and not focus on a large pink tongue. Also I like your DOF, personally. I think if you went with the foreground more in focus you would loose the subject. Personally I feel this is a great piece and nice addition to your collection. Good work!
having more depth of field would have saved this image, because you chose such a wide aperature, probably with a macro lense-to get the detail in the icicle, you lost detail in the tongue, and that, to me, is essential
