I must say that it will take me some more time to get used and to use HDR etc techniques. But once I accept it and learn how to use it - beware of the SAM !!! LOL
I think you did a great job on hdr! The grey sky works well with the white barn and slate-grey roof... and the yellow (mustard?) in the field is a great counterpoint. That said, have you considered converting this to black and white to see what you have?
