I really like a lot your work. And this photograph is definitely one of your best, both by the extreme technical accuracy and the great human and emotional strenght. A photo that all photographers wish they would have done.
This picture really draws you in and then leads you through to the two faces of the women and then the three wonderful smiley faces at the back, a truly wonderful composition, I too agree it is one of your best. Absolutely fantastic and a huge vote from me.
