The subject matter isn't particularly interesting to me, but NICE smoke... reminds me of Kiwi's Fire winner. I like the off-center composition, though the last one is a little too close to the edge.
This is so real I can almost smell the smoke. I hate smoking, but I won't vote you down for it. Having the filter edges aligned would have made it perfect. 9
Whoa, the smoke looks meanicing, as if it has eyes and horns. Nice capture of the smoke. I think the image would also have made a nice shot with the left side cropped off.
