Mario, Beautiful color tones in the grass. From my perspective, however, it is a very busy scene, a bit of chaos. Personally, I struggle with such scenes. If I may, I suggest two changes of a similar nature;
I would blur the outer edges on the color and a B&W version of the image. I know the B&W maybe sacrilegious to you because of the great colors, however, B&W brings out more contrast to isiolate the center of the grass, giving it a better subject / focus point. Just another perspective, I do appreciate your artistic vision.
Works great in color and black and white !!! The lines and sharp to soft image i really feels works great. Not a perfect world out there. Beautiful shot !!!
