Well, interesting the assumptions we base our judgments on.  I was  
assuming the pavement and doorsill  were stone, which often has a  
slight blue cast, especially in the States where slabs that size  
(even on the west coast)  are most often cut from Pennsylvania  
bluestone.  But even concrete generally has a slight blue cast in  
shadow, so I wasn't concerned about the slight blue in the pavement;  
that seemed natural to me.  After reading Loris's comment about the  
image being heavy-handed on blue, I downloaded the picture into  
photoshop and played with adjusting the color curves.  Adjusting the  
blue or red curve even a tiny bit to less blue or less cyan just  
shifted the image to a yellow or red cast in the image, suggesting to  
me that the blue/cyan layer was fine as it was, whereas adjusting the  
green curve to very slightly less magenta made the image more neutral  
overall.   And looking at individual CMY values in areas I thought  
should be neutral, like the doorsills,  gave values that were skewed  
toward M, not C.   Not a totally scientific way to judge the color  
cast of a print, but enough to satisfy me that I could trust my eye  
when it saw no blue or cyan cast in the image.

"Heavy-handed" is a pretty strongly negative term;  I probably  
wouldn't use the term "heavy-handed"  to refer to the color balance  
of a tricolor gum even if there were a strong and unmistakable cast,  
rendering the yellows as green, the oranges as grey and the reds as  
purple; I'd probably just say the print had a strong color bias.      
As I said, I do see a slight  magenta cast, but so slight that it  
isn't really even worth mentioning, and I never would have mentioned  
it except in response to the "heavy-handed" comment about the blue.   
I'm glad to read that in spite of the criticism, Loris does think  
that the print was well-done.
