Nice use of textures with the field contrasting nicely with the smooth sky and the clouds between them. There is a little noise on the sky which is a shame. If I might suggest a little more contrast might also enhance the image, or perhaps using a red filter on the conversion to add some drama to the sky.
Nice capture IMO. Noise is minimal, at least on my screen with my old eyes. Little more contrast in the flowers field might help. Again, just my opinion.
This is a very nice photo. Since the sky is mostly vacant, I might have considered cropping out a bit more. I would have liked to have seen this photo in color. My father is color blind, and he's never mentioned to me that this is an advantage to him. A field of flowers with a dramatic sky full of puffy clouds seems like an ideal color shot. Additionally the horizon seems to be dipping on the right a tad.
