Camren is so pretty here. In the first gif she has that sort of very Greek statuesque smile, and in the second one she's just ethereal.
That rooftop scene is perfect acting, I just want to nitpick a bit that that ledge is very wide (around a foot), yet Selina had to teeter to walk on it. Granted she wore high heels, but those were block heels. If that ledge was only wide enough for her to put one foot on and/ or she was wearing stilettos then I'd understand. A normal person without fear of height can walk carefully on heels on that ledge, not teeter.
