Reminds me of the purgatory in The Lovely Bones by Alice Sebold. The clouds extending far back with the sun shining through is elegance defined. The field of sunflowers makes me smile and want to visiti this place. Your use of persepctive in this photo brings out the colors of the sky excentuating the clouds and sunlight pouring through them. The dark line of mountains in the far distance stands out amongst the field and sky adding for a nice in-between.
It is hard for me to see something on the down side of this photo, and the only only thing I can give advice to improve upn is maybe add some contrast to the flowers and greenery so it is a bit more defined.
All in all, a truely beautiful piece I shall remember.
