The smoke looks amzingly like silk. Very nice, although the ashtray looks a bit too bright in comparison. It would have been much more interesting to have had the smoke the brighest focal point. [7]
Far too much 'bright, normally exposed' subject for my tastes in this challenge, I'm afraid. If it were, say, sidelit dramatically so the smoke showed and the cigarette and ashtray were more suggested than shown, quite possibly a 9 or 10 for me. As-is, though, 5.
this is really nice, but there's a couple of things that bother me. one, i think, is the shallow depth of field. i'm usually a big fan of this technique, but i think it looks a little odd with the glass ashtray and the cigarette. the sharply focused end of the cigarette and the very nicely lit and focused smoke trail are really great parts of this image, though.
maybe if you move the subject to the opposite side of the frame, the blur wouldn't bother me as much. i think right now it's kidn of blurring off into a hard edge of the photograph, whereas if it were on the other side it would blur off into the blackness of the background. anyway, overall a very nice effort. 7.
