I like it. It strikes me well. In my country there was a campaign against alcohol behind the wheel. What they did is that they showed a series of "strong" shots, brutal showing accidents with no "censor" sign
I think the concept here is sound. I'd like to see the color of the stopsign a little more vivid and sharper. I don't mind that evertyhing else is blurry - but I think for this composition and message it would be stronger if it was. I like the off centered placement of the stopsign.
