I like what I can see, but the blacks are so deep that I can't read more than posture and position. The girl's expressions and for that matter their actions remain opaque. One is standing, one is bending over ...something, and reaching for a....something. The mood has eaten the motive.
I love that this image is incomplete, teasing you with just enough information to know where they are, yet not enough to know if they are real or just visiting angels.
(Not voting) It wasn't until I began looking at this on the laptop which is brighter that I now see that the two girls on the left are laying flowers on a gravestone. My first impression upon seeing it on the PC (in which both far right and far left are cast in darker shadows) was that it was the two girls on the left were playing and excluding the girl to the far right. My thought was that the action of excluding the little girl was sad - even though I could not see/read her expression because it is dark and in shadow. Now I can see that the two girls are paying respect to a loved one who has passed - the problem still rests in that facial expressions and the tombstone that is flush with the ground are too lost in the shadows to convey a strong sense of sadness - there is a touch of sadness but it is hidden by the deep shadows that fall on the opposite sides of the photo right where they need to be visible the most. Since this was Advanced editing you could have done a little dodging and brighten up the areas on the girl's faces (but not too much) and a little more on the left side so the graveside is a bit more visible.
Moving. Great photo! Good luck. And by the way.... I love that you didn't title it. Photo should speak for itself when provoking emotion. Good luck and I think this is a top contender.
