Marco said exactly what i would have said so i wont waste my time typing out an answer that in essence would be exactly the same as the previous post so to save a lot of time and effort i will just copy and paste his answer into my reply.
It's a very sharp macro lens Tim. You have done well on both these subjects but the first has more appeal and has great sharpness in the places that count visually. The second suffers a little in that area with the back a little soft and unfortunately the eyes tend to gravitate there a little.
cheers
shane.
see ... saved heap of time
Me too Tim
Saving/preserving time is important up here in Montville.

Ps Come up to my place, with that lens, and take some bug and flower shots one day.
