You were after something that celebrates the dark, so I disagree myth those who want to adjust the "underexposure." It intrigues me to see it cropped severely at the top ("sunset fatigue" on my part?) until the dark meets the edge on the left. Then, perhaps a slight lightening. Either way, the dark then wonderfully brings out the lovely but subtle pond colors.
A very enjoyable shot!
Glad you like it Bob. Your crop does sound a bit tight for me - not enough contrast for the silhouette to sit in? Of course, the pond is an important element with lots of hidden interest, but that seems to be the problem for most - too hidden. Many thanks for your considered critique.
