beautiful picture and this whole serie is really awesome. I love the model's clothes, how they flow with her body and really matches her expression. A really powerful photograph, to conclude. Very emotional and very nicely done. The blurry background makes it all even better! I actually can not think about someting in particular that you can do to improve this picture, since it already is so amazing but I would like to see it cropped in a different way. Maybe not square but vertical I am not sure if it would be better, but I think so.
Congratulations to an amazing photo! Have a nice day
