I need a investment-stage poster created.

We're producing a remake of the classic Frankenstein, and we need a poster to shop the idea to investors and studios. We're looking for something that looks good at the 11x17 inch size. It will have the working title "Victor Frankenstein, and the line " Playing God has its price" as its only text. We've attached a mock-up made earlier that we made in house, but we're hoping for something better. We can provide the stock photo if you want to use it as a starting point.
