Cig butts don't make for an interesting subject, but yours has a nice, aesthetically pleasing presentation which draws strange interest from me. The trail of smoke is also a nice touch.
I like everything about this shot: the technical "merit" (forgive the pun); the cropping; the hint of lipstick on the cigarette butt; the smoke; the broken cigarette in the ashtray. One of the best shots of the challenge. Excellent job! 10
