First of all, allow me to congratulate you on your project - it must be really a great amount of work colecting voices of people from all around the globe to complete this task! I wish you all the success!
About the poster, I'll be a little critical. If it was up to me, I would have made the background with some nuance instead of solid black. And second:the claw marks would have left more tоrn edges. I believe thus it will look better while preserving the main idea.
