As written inmy comment, the boy's eye at left is too attractive, so crop the picture to remove it.
Then levels to get white and black hues
Increase sharpness to have the white dots in her smiling eyes
What do you think?
My Dear Bulent,
I had been receiving your photos and viewing them but was too lazy (the excuse of being tied-up)to respond. Apologies. Felt very attracted to see this shot. And so historian like comment perfectly aligned to TE spirit.
Did a WS. Hope you like it.
