Very nice focus on a single element. I would have moved the branch out of the bottom right portion of the frame, but the overall mood of the photo is still nice and you got so much detail... I like it!
I agree with memsong.. the branch eliminates the nice grassy pattern but perhaps that was the effect you were aiming for: that nature is random and hardly uniform. Then again, maybe I'm reading into it too much. At any rate, I like the macro!
Really nice job with the focus. The blades in the center really draw your eye right in. The hairs and water drops are an added bonus. I do have to agree with the others on the twig (if it were more or less dominant it might look intentional, but it's just the right size to confuse my attention), but all in all very nice.
