I really love the colors of this photo! The orange of the sunset in the sky and on the water works really well with the red roofs. It really gives the photo the Mediterranean feel that it needs. Makes me want to take a trip soon!
For a critique: I don't know if it would have even been possible but I feel that either having the town filling the frame or having more trees and greenery filling one side would have been better. Maybe also more of the water and boats visible. Another minor preference of mine would be to have the clocktower more 1/3 of the way on the left with the water to contrast city / sea.
