I absolutely love this image - its a different angle that I have never seen before of the Eiffel Tower.
Do you have Photoshop? I would be inclined to convert the original image to a black and white HDR photo. For now though if your not that experienced with photoshop, I'de convert to B+W and increase the contrast.
My only criticism of the photo would be that the "top" trees are too close to the tower in the image, framing the Eiffel tower central in-between the branches would have made this photo even more outstanding than it is now!
I say I would love to see a B+W version - but I do really love the colour enhancing you have done!
