Good exposure, pose, BG, and low angle. The soft light really helped here. I'd personally prefer the subject smaller in the frame, and I find the black strand next to the legs distracting - easy to eliminate vis clone and patch tools (if you are so inclined to do so). The eye is nice and sharp!
Thank you all for the kind feedback. Agree on the tightness in the frame. It was one of those occasions where suddenly it decided to come up real close and check me out lying on the ground. There was no time to take off the 1.4TC.
