I have a problem with this photo...

The problem is this: I have no idea why I like it. I just know that I do.

To provide some context, I was fiddling around with my 75-300 kit lens in preparation to snap some birds nearby, when this guy wandered into the shot. I didn't even pay that much attention to what was happening. So I got home, dropped all the images on my PC for editing and all that, until I came across this photo, and it's been bugging me ever since. The original was in color, out of focus, and over exposed, so I messed around with it until I landed on what you see above.

I then decided to get some outsider opinions on it. Do you like it? Why? Can you spot some photography theory hocus-pocus that could possibly qualify it as a "good photo" even though it was completely accidental?

Looking forward to some discussion on this one! So let me know what you think.
