This could have been a great shot if the model had been posed at dusk or at night, with a beam from the lighthouse as the source of illumination.
(...Unless the point of the picture is that the lighthouse is no longer in operation...)
To me I would like to see more DOF and a better sky. Too much of the image seems out of focus to be pleasing to me. I wonder if it might have worked better at twilight when the detail was still visible but the light was on in the lighthouse.
