Was it your intent to make the illusion that there are equal amounts of water in the 3 glasses in the background within the refraction by creating a line with the edge of the water? Either way, very nice, and I like it.
I expected a few shots like this in the challenge. I have nothing against them but this one seems a bit too busy and crowded. Could also be a bit brighter I think. But congrats on getting the reflections with no strong reflections from your light source.
