I really like Light Houses, and this one doesn't disappoint. I only wish the composition was a bit different, showing more sea to the right, with the light house farther left, and maybe down some. Just a bit too close to center for my tastes.
Maybe you should change the composition so that the lighthouse is on the left edge, leaving the head and showing the more of the wintery gray water. BTW, I used to live on this point and no this lighthouse well.
Great use of black and white. I think I'd like the lighthouse a little more off center... maybe in the upper left hand corner to simplify and also see the end of the land on the right.
