Hi Joshi. It looks like you're off and running with the new lens! You really nailed the focus on those beautiful big eyes and you have excellent detail throughout your DOF! I like the pose and the tight comp. I would suggest running some NR on the background. Overall, this is very well done!
You and that 100mm lens seem to work well together! The eyes which are the most important of this capture are as sharp as can be! Steve's suggestion of running NR on the BG is something I agree with. This is a good capture that would have been over the top had you been able to get the palps in focus.
