Wow, this is pretty cool. I must say that I am a big fan of this concept and this motif. That's much because it's creepy, but it's not obviously creepy. From a distance, it looks like a typical softness-motif, because of the butterfly and the light and the laces.
The cut in her arm looks like a typical suicide-cut, which suddenly makes the whole thing look quite dark, from my point of view. I also know that there is butterfly that sucks blood from dead animal, which is one of my quickest associations. The title "Nectar" also makes this clearer.
What's interesting, is that after looking even closer, the creepiness goes away. What I actually see, is hope, life and love, if you know what I mean? Because of the butterfly, that is associated with freedom, and the cut, that is associated with sorrow or even death.
I love the photo because of the symbol that I see in it.
When it comes to cutting, I wonder if it would look better if the picture was cut before the black background comes. I think it would look cleaner, and when I scroll down so that I can't see the black background, it does even look better.
I have to give you 5 stars for everything in this piece. I will start my critique by telling you, that I am a traditional artist and not a photographer; however, I do enjoy photography as much as any other person, and I am writing you this critique because I saw you requested one AND because this piece managed to surprise me. Surprise is, to me, a very hard thing to achieve as a visual artist, and even when we succeed, it's a short-lived surprise. But with this piece, the moment of surprise was - for me - longer than normal, and when I realized, that this wasn't just a pretty photo, but that there was something hidden under all the beauty, I was astonished. Then I went on to feeling the feeling I think you want to achieve with this: touched. Touched because this piece speaks for everyone who has felt lost, who has felt like there was no beauty left, maybe even nothing to live for. For all the moments that we have cried, for all the moments we have wished to move that butterfly so the whole world could see that we need help and that we are not perfect. That is what I get from this photo. It's disturbing, but it's necessary, because it reminds us that there are people who are afraid to ask for help, and that we need to see behind the masks sometimes. As for the composition - such beauty. The white, fragile dress is wonderful, the butterfly well chosen (I am painting one just like it right now, what do you know) and matching the background is a nice touch. The white enhances the fragility and the hands look white like they belong to a ghost, which is sometimes all we are, isn't it? When people don't really see us, at least it feels that way.
