lovely scene - the clouds are nicely exposed, the field is warm, and the slope of the land pulls us in - but cropping the top of the tree, the heavy vignette in the upper left take away a bit
Great sharpness in the central tree. Nice colors that are saturated well without being overdone. I'd like to see the whole tree however. That aside this is a pretty good image.
It's almost like a painting. Very nice. I'd have cropped a bit more off the right side to get rid of that red roof and take the tree more away from the center.
