Very nice shot. Next time, when you crop, (assuming you did) straighten the horizon. But please understand the horizon and minimally cropped feet are about one percent of this photo. Good stuff.
Terry - the brightness has nothing to do with "relatively fast 50mm f1.8 lens", its just a good/correct exposure. Notice his exposure was f3.2 so even is he had used our favorite 28-70mm f2.8 lens, the exposure/brightness would be the same.
Very nice. I wouldn't worry too much about the foot of the defender that's a tiny nit pick since she isn't a main subject. You've got a good exposure, well focused shot that isn't killed by cropping or noise reduction. I'd take that any day over a washed out or OOF picture with all feet in the frame. Nice expression and very nice framing!
