the lighting is not very attractive here, and the diagonal line isn't working either, for me. I get the relationship between the butts and the sign, but I personally don't think there's more to this than that.
I like the idea, but I think a different angle would be better. I would have tried it with a higher angle, with the no smoking sign at the top of the frame and the cigarrettes and the bottom of the toilet in the bottom of the frame.
