Lucky to have this vantage point. As such, the overhead look can often score on its novelty alone. But you've taken this a step further and given some thought to composition. Very nice.
Beautiful lines! Love the composition as well - the square crop, the two leading line patterns, the harvester being where it is at the intersection. Wish the picture was underexposed a little - would have avoided the blown highlights on the harvester, as well as made the lines more prominent I think.
