Stuunig sky and great composition. I really like this shot. I would try boosting the colour of the grass making it slightly pop more, but what do I know, ;-)..I just wish I could take sky shots this good.
I dont know where you live but I think a visit is in order.. the skies here NEVER look as good as your pictures.. and I have been looking...In this pic I like the style but maybe if the little shack was offcenter I would apreciate it more. That being said, this is a great shot...
