Skate Deck Poster Story

The Story of this poster just makes me feel that it should show how the blob is by giving it the effect that green goo is falling around and then when it crosses a line the goo turn black.  The goo will also fall on too the text so that it gives a effect on the text as well.  Then the skate board will be on the bottom right on the other side where the back is green and the goo is black.
