If that were me sitting on that cigarette, I'd be scared to death. It's so life-like and amazing that I'd be afraid to jump away, let alone onto it, from it, for fear I'd literally fall into a canyon. Awesome message to people who smoke to encourage them to stop smoking.
I love illusion art. This is amazing yet it looks more like a carpet, cause of the edge around your piece. i also have issues with your sign... its over the edge of the piece which makes it look out of the illusion as if its sticking up beside the white paint tube. Yet its ancored in the piece with the bracket. So this area throws off the illusion to me. other than that. you have a great imgination
