Julianne, this is so pretty! The focus is very sharp. The only issue here is image grain. It must be due to a large crop? I'll send you a PM with some ideas for reducing the grain, as this image would have scored MUCH higher without it.
Love the lovely green hues seen on the butterfly and the leaf it rests on. Very nice sharp detail on the wings and the textures of the leaf. I like how the DOF is shallow and that it has a bokeh look background for the butterfly to pop off of.
