Thanks Akul! Yes, it is ice that I'm actually standing on. Just a frozen pool on the road. The grain is very small bubbles in the ice, but there's also some noise of course, mainly because of heavy contrast enhancement.

This image is just amazing. It took me a while what it was and realized it was probably crack on piece of ice? High ISO noise? is adding a very nice texture, adding more painterly = or graphite drawing kind of feel. Amazing.
