Wonderful shot. Love the emotion and tenderness you've caught here. Nice toning. I wish there were a tad more separation between the tops of the heads and the bg. Still lovely.
Very nice moment of intimacy, only minor thing is that (i think) one of the lights in the background has quite a strnge effect on the image making it appear as if the girl is either sticking her tongue out slightly or has very odd shaped lips, possibly a touch of dodge/burning may have helped
Pet peeve... chopping off fingers when most of the hand is in shot. The green sepia looks terrible. But you've caught a nice moment. It almost looks posed, but I'll give you the benefit of the doubt. You could crop much tighter, there's way too much negative space at the top. I don't like it that you can't read the writing on the t-shirt, be careful if there's text in a photo. It makes you want to read the rest of it.
