I like rule breaking. Esp. in a case like this where you have something to show in the foreground that needs all it's parts. If you try covering the bottom some to make a faux-thirds-rule photo, it's just not right. I think there can be creative ways around this....maybe you can do a negative of the same shot and put them together side by side... maybe use PS to color 2/3 of the picture to help give in to some of the ROT idea. Maybe crop at an angle to change the feel entirely.
I can see where the others are making accurate statements, but I think you could save this one with a little creative work on it.
Now, being really picky aside, most people would say that was a really cool picture. Including me.
