I really like it. When I first saw it I thought it was in slow motion, looks very calm and serene, but then when I thought about it the image of someone bashing a rock with another I get the image of a fast, hard and powerful tone. You pulled off this torn effect perfectly by showing the rock at rest, not in motion. I'm not sure how a larger DoF would look or what it would do for me, but if anything I'd like to see a little more of the bottom left corner, where the entire rock is visible. It would look more serene and tranquil IMO, as it is now I look and wonder how big the rock is, what's out there further, etc. Well done, I really enjoy it the way it is though.
