It's really a nice photo. But I think the boats should more look like miniature. Perhaps a blurry foreground would make it better? Or less blurry background!
Because of your photo, i also did a Tilt Shift Experience, you can see it here: [link] But i have also the problem to create this "modelmaking" style. It should more look like little modelmaking houses, but it did not (:
I'll keep that in mind if I fix this one or for my next trial, be sure it will help me
