At last, Lucio, a good tall lighthouse; most of the ones we have seen recently have been rather squat, although well photographed.
The only thing I wonder about is cropping away that mast on the far right, and a corresponding amount from the top. Alternatively cloning it out might be worth a try.
A very nice and tranquil scene. In addition to Geoff's suggestions, I might try cropping a little from the bottom as well.
That is one impressive light house
Very nice. I love lighthouses.
