this would probably score higher with 1) better smoke, and 2) a different title. i've seen some people blow smoke through water (and i'm not admitting anything here), where the smoke looked actually intoxicating. you might want to go back and work on this some more
The clarity and colors and very nice. However, the subject probably won't go over very well here, and the composition could be better too. Not enough emphasis on the smoke.
Two images, this one and "Toke", are both similar in that the subject, "smoke", is inside a bottle. Both, to me, have the same shortcoming: the smoke is very much reduced to a lesser subject position by their container - and to me, the main subject should be "smoke" in order to make it more effective as a "smoke" entry. But, that's just my way of looking at it. Good luck in the challenge.
I like this a lot. It's an interesting image with subtle colors, great focus and decent composition. I would have been able to score it higher if it had a more obvious tie-in to the theme.
i couldn't see any smoke, but i had a nother look and i think the smoke it the yellowy stuff at the top of the bottle - i hope that's true because i just upped your rating because I love the bubbles also! :)
