Meant to come back and leave more of a comment, but time ran out (as ever). I like the mood here, and your capturing of it - we've not had so many rainy days in the UK recently, and this summons up that greyness and reflectiveness of the world, without resorting to black and white. The deception is pretty subtle too - it so looks like a cobbled street, but that would make it the world's largest cigarette.
Interesting image. Took me a few moments to see the cigarette butt. I like the composition, the textures are great. Lighting looks good and the focus is decent, though I'd rather it was mostly on the cigarette so it didn't get lost in the photo. The overall image looks a bit gritty like it was oversharpened. 6
