Colors are great, as well as the movement in the water. If I had to pick a nitpick I would think about moving the tower more into the classic rule of thirds orientation. Just my two cents.

I really love the 'pastel' quality of this image, you have caught the motion of the sea coming back on itself at the perfect moment. Beautiful. Margaret
Welcome, I'm relatively new myself. Splendid dynamism captured in beautiful mellow light. No need to straighten the tower, after all Pisa's not far away no?
