I agree with the above about the girls expression or projected feeling but this image, with the controlled contrast, empty clear space, beautiful explanation of her profile lines, gives serenity to my eyes. It is a gentle sinuous travel with plenty of void to reflect about it.
She looks concentrated inwards, remembering perhaps, a personal moment nonetheless in which we are allow without intrusion, as another layer of serenity.
I also like the shot
Thanks Almass!
