I found three pieces that might work well with my animation all from newgrounds.com
His Final Act by Jay B (Hamstercake) @ http://www.newgrounds.com/audio/listen/391657
Silent silhoutte by Mark Spark @ http://www.newgrounds.com/audio/listen/406489
The execution by Oskar Nyman (Ossikater) @ http://www.newgrounds.com/audio/listen/374639
I have added the links as I dont know how to embed sound but these three have the essence of creepy and the dramatic so I will try them out against my animatic and see which one fits better.
