Need Some help with retouching.

Hi All.
Friend of mine asked me if I can restore his photo made in '80s

Photograph was in the frame behind the glass, and after the glass broke he figured that he is attached o this image more than he thought. Now,

I scanned the photo, cloned the patches but I have a trouble to restore blueish color on the ice..
Perhaps someone here can put me in the right direction or try to fix it.
Below is 1) original scan,
2) cloned patches ---> this is large image ---> original size
3) B&W version and
4 and 5 )2 colored version.
Any help will be highly appreciative.
Thank you,
Jacek
