ESCAPE - Dodge and Crumble - Colgruv

My general idea is fairly straightforward -- a Dungeons and Dragons-esque combat scenario in which a character dodges the crushing attack of a monster three of four times his/her size. However, I want the scene to focus just as much on the motion of the environment as the two characters. To this end, I've dedicated a segment of my mood sheet to capturing the motion of structures breaking, crumbling, and falling, presumably as they are struck by said large monster.
