Color, saturation, brightness, contrast, and hue are excellent!
The tree does seem a bit soft in comparison to the grass, but that could be a bit of illusion.
I too would have like a bit wider frame. The tree travelling off the edges is a little less satisfying.
I would really like to see you come back and take this photo again at sunrise, sunset, or on a stormy day, to fill in the featureless sky. All that empty sky is a blank canvas waiting for your brush.
Very nicely done, and should have scored a bit higher.
I really like this. My only suggestions would've been to zoom out a little so the entire tree was in the frame and possibly do this at a different time of day (sunrise or sunset maybe) so that the sky was more interesting.
grass is sure nice in this. overall I give the image a 7. not sure what i think about the sky/white area...and there seems to be some 'surviving" green in right side? gl in challenge :-)
