Really like the first one, the composition is strong and classic which suits the processing really well and the sky is spot on.
The second one just doesn't sit right and I think it's a combination of the lobster pots in the foreground blocking access to the scene and the sky whith it's blown highlights.
The third doesn't do it for me at all the vintage processing seems a touch over done and the powerboat in the foreground really destroys the vintage feel.
