Nice tight crop/composition with great detail. I think the leaf mass at the base and a bit more of the upper left border leaf would have presented a bit less severe image. That's more a personal preference, of course.
Think about the photo before and after, never during. The secret is to take your time. You mustn't go too fast. The subject must forget about you. Then, however, you must be very quick.
