My first thought was WOW!!!

First of all the composition. A simple and effective one with lots of nice graphic details such as the blades on the windmill. The silhuettes are awesome and give this photo a mysterious feel.

Your choice of B/W increases the effect of the composition and the silhuettes, and make this photo even more facinating to view. And the vignetting gives the photo that little extra to sell it to the viewer.

With the clouds and the grass framing the main subject of this image in a very nice way. I have to admit that photos such as this really inspire me to try new things. (Maybe a little to many superlatives there but I ment every word)

I love windmills because either ancient of modern, they are unique objects that call to our memories and imagination.

When I first saw this picture, I instantly recalled a very old Oscar-winning Disney short movie called The Old Mill from 1937, where the construction and all the little animals living inside of it face a huge storm during the night... but in the end, the terrible wind -what gives purpose and life to the windmill- is kind enough not to destroy it, and so nature and man's creation find a way to coexist together again...

End of the aparté, this picture sums up perfectly how man can be able to work with nature without destroying it.

The composition goes in that sense : the crossing verticals/diagonals (windmill -man) and the horizontals (horizon, skyline and the wind -nature) give focus to the subject, but where it could have been easy to make each wing point to a corner of the picture, the artist chose to place it outside of the centre to leave space for a tree to show -another great demonstration of this little story!

Technically, the picture is sharp and perfectly exposed, and I see the use of vignetting more as a way to show different palettes of the rich sky than another focusing element. Maybe the little white fringe on the right tree's branches could have been avoided, but that's no big issue.

This is one of the pictures that you want to look at for a long time, just to get inside of yourself as you would get inside this windmill : maybe shelter for a while, and come back with sustenance for your heart and spirit.
