Hi Slawek,

Welcome to RP! :pleased:

Looking at your picture, I think I understood what you meant by 'colour circles' .... If I'm not wrong that's called 'banding'...

To remove 'banding' I, usually, only add a bit of 'noise' but, in this picture, it didn't really work so, I did the following:

Duplicated the Background Layer.
Selected and feathered the background.
Run a strong 'Motion Blur' on the selection.
Added a bit of noise.
