Can't say I understand your motive here. But I've taken many shots that in later view elicited the same feeling wondering why I did it. But to present this you must have a sensible reason which is lost to me. I note the bright circle of confusion that is the same color and a few dots and it stands out from the dominant blue-grey of the scene, but ???
Your too competent for me to think you don't have a solid reason for it.

پر از حس و حرکت و در عین حال آرامش، لذت بردم

I thought about Hugh's candid comment (thanks!).
And your posts of the last days.
My first thought after seeing this pic on sunday was : "she turns away!".
It is for sure a picture of your series "young females's backs" (ad hoc i remember 6).
Do you begin to give us a retrospect of your work of the last year (and begin to accustom us to ddoiless times)?
Or is the weather to bad to take a walk (this is no reason for someone like you!)(except the flu did catch you).
best reason would be :
you're too occupied with watching Junior growing for making new pictures *smile*/*unserious joke*

I wonder about what pictures you'll present us the next days. And think about it....

@ Ali : it's "just not cricket" and pretty unfair : please struggle with english like i do! ;-)
