Help me Choose - Barefoot Babies

Remember back a couple months ago, when I wanted to enter into a photo contest, but I didn't know which picture to choose, so you helped me, and I sort of, kind of won a little bit?  Well, there's another contest (nothing big. Just a fun one from a forum) and once again I don't know which image to choose. Help me, please!!

The theme is FEET. Which one do you think I should I enter?

1)

2)

3)

 4a)

 4b) Which version?

I have to turn it in by Monday, so if you get a minute, let me know what you think.

Thanks, friends!

Lucky Number 3!!!

The deed is done. I've sent in this photo - Number 3.

I'll let you know when they post the results. Keep your fingers crossed!!!
