Crit for Visual Equations

We had our Visual equations critique this afternoon and the tutors didnt hold back. which is what we need i think if we are to start getting used to the way industry is. But I was told that my idea or concept is good, but thw way it has been executed needs some work. I was told that the one line remarks i have blended into the gravestones arent enough to create a third meaning..a third meaning in which i wasnt very clear about. I was under the belief we were taking 2 concepts and using juxtaposition to create a collaged set of images. i was a bit lost when they started talking abot a third meaning, but yeah. So i shall go home and resist the urge to play online poker and try to crack on with some work..leading up to the deadline on wednesday.
