I love that you are able to shoot a bit for yourself on these assignments. I envy your position - enjoy it!
I apologize if you weren't looking for a critique, but I'd like to offer a small bit of constructive criticism. The nuns praying is a great moment, but I would offer a Robert Capa quote: "If your pictures aren't good enough, you're not close enough.” Good job taking the image and recognizing the moment - it just seems to me that the image doesn't fully work with the impact it could have. I realize that you want to include the crime scene elements in the foreground to give us some context, but in this situation without a caption I don't feel we can really see what makes the moment special because all the elements are too spread out, and the subject - the nuns - are too far from you. The photograph feels like you likely felt - outside of what they were doing. That these women would feel compelled to pray for someone's soul who they likely did not know - very moving - but the image doesn't convey that. Maybe if you had moved in closer in subsequent frames you could have some award winning material there - just my two cents - I just see a lot of potential in the access you have - keep working and thanks!
