I'd like this better without the paintings on the wall in front of her. They really disturb my focus on her. This response may be a self awareness one though. Even though I'm not there, I feel self conscious looking at the praying nun and so I keep looking away at the paintings so as not to stare and appear rude. Does that make sense?

surely nuns are never alone. I like the colours.

difficult lighting and composition, nice idea but would probably need a few more variations to get it right
