Beautiful as usual.
May I tell you what I think the thought process was. So in the color version, the yellow green draws the eye framed nicely by the trees and dramatic sky. Pleasing color palette.
It seems that in the B&W conversion, the desire to draw the eye to the yellow/green area of the landscape was a bit overdone. Maybe it's viewing a jpeg on the screen and not seeing the print. There is a loss in subtle tonal variations that I see,and like, in the color but not in B&W.
