After seeing your ballpoint pen shot, I was really expecting an even closer shot, maybe of a very small, like the size of dust, insect filling the screen like the one at

The third one is nifty because of the magnification of the yellow things. I felt the other three would be more likeable by myself if all the ends were in focus. They are so close to the one in focus, yet are out of focus,slightly, that is became more of a distraction to me.
Just my opinion.. I like nearly all of your other pictures in your other posts though.
