I'm going to enter a photo contest... which should I use?

I like 4. A lot of emotion in that shot.

I wouldn't have entered #5. The composition isn't very strong, and you cut off the top jelly fish, and they are soooo close to the edge, then there is the black empty space on the left. Consider this matted, and you are losing 1/8th to 1/4 inch more of the top jellies.

But good luck!

ok thanks for the heads up. I entered #6.
