|Greetings from the Critique Club!
I can see how some thought you did selective desat here, the tree is scorched enough to give that effect. The dead coals in my woodstove have that same tone to them, if they haven't been reduced to ash. The vibrancy of the green does a lot for this shot.
Compositionally, I feel a lot more could have been done to draw the viewer in. It has a snapshot feel to it, with the crop being quite tight on the left, and the bulk of the tree forms a little bit of a dead end. Also the very high ISO, for a stationary object like a tree, is a little fast. FWIW I notice that I start to get noise at over 400 ISO, so you would want to keep it as low as possible. The aperture is fine, the shutter speed could probably have been slowed down quite a bit.
Artistically it does make a very strong statement, that of rebirth after such devastation, and the other areas of green in the shot give a sense of hope. Overall a pleasing shot but I feel you could have told a much stronger story.
Feel free to PM me with any questions,
