I love that first one particularly -- it's like an angry alien eye, lol. The others hit me like abstracts. If I had a criticism it would only be one thing: watch out for blur in the foreground. With some subjects (and maybe these) it's unavoidable but for some reason the human visual system finds foreground focus and background blur more pleasing than vice versa. However, that "rule" too is sometimes made to be broken! Nothing is that simple, lol. In fact, I think the second photo breaks that rule well using the unfocused objects to "frame" the subject.
But that being said, sometimes you have something in the foreground that isn't the subject and can't be in focus without taking the subject out of focus. Really busy areas in terms of depth are hard to macro in my experience -- though I'm sure some find it easy I've had to work at it. That's why you don't see a lot of macro work from me, lol!
Thanks for your comments on my work as well.
