Advertisement campaign

The poster that i made i belive should be shown online on sites such as facebook to viraly market it, the poster cant be shown outside in public because of the blood as people or children may see this and feel sick or scared. I would like the trailer should be released before the big summer block busters for example The Avengers  or a horror like cabbin in the woods, the second of the two would be more aceptable because it is a horror. Because we are a small company i belive that we should have the trailer before films at film festivles or before a "indie" film at a cinima.
