I'm Ready for My Close-up

Thank you to everyone who responded to my "blue" assignment here and in person. It seems the ring has it!

One of the things that I love about a photgraphy class is that it forces me to really compose an image and take into consideration all of the elements that comprise a good shot. My second class assignment is a close-up, and must contain all of the general rules of composition; varying levels of interest, diagonal lines, an object in focus, and a repeated pattern of some kind. So here are the new contenders.

So, which, to you, fits the bill?

Blue

So, I'm taking another photography class and the first assignment is ... you guessed it, "blue." I have to choose my best shot to submit, and since I have such discerning and aesthetically advanced friends, I thought I'd turn to you to help me decide. Which of these images not only speaks to you of blue, but works compositionally as an image?
