OK, tried it rotated a little. That's actually his butt in your face, not the most appealing subject to really want your eyes drawn to (the ant or the food).
Tom, I came so close to having a no bugs rule but I figured with JDU's 7D in the shop I was safe, LOL (I hate bugs). And bugs are food in some place in the world. Interesting shot. Did you go out an find ants or did they come to you? I think I would have liked (not really) to see the big ant a little more into the picture. His (I assume it's a boy ant) position seems to be moving off the page and I find that draws my eye away. Or it could be that I'm just averting my eyes from the ants.
