I know I already commented on this submission, but it's too good, not to be analyzed in depth.
First of all, I am impressed about your choice of stock. You saw things in those individual submissions, that amazes me. It shows a keen eye on what works together.
Second, the whole idea of your submission is VERY original, and I regret not having it for my self. A dress made of escaping butterflies...wow! That is original, and deserves a high-five.
Third - execution; there is next to nothing that I can point my finger at here. The shadows are just right, the dimensions between the different stocks are spot on.
Now...the critique. I have only one. I love realistic manips, so my critique is based on my likings, and not all of the positives mentioned above...it looks a bit too 'dreamy'. Like taken out of a fairytale. I would have preferred a more realistic look and feel.
THAT SAID!!!... I simply love this one, and you did a hell of a piece of work!
