Neat idea, but needs a little more light or contrast (not much). There's not enough definition to identify these as garbage cans -- not without a good look anyway, and that's something that most voters here won't afford you.
This photo is on the right track......I think it needed a tripod, as there is some mild blur. It probably could have used a bit longer exposure as well just so that I could make out more detail of the subject. It's hard to know what I'm looking at.
