Boarding place for ghost ships

One more long exposure from vacation at the seaside.
Filters: Hoya ND400 + Singh Ray Gold'n'Blue CPL + Singh Ray ND-3G-HS
Rest of the technicalities is in the details on the right

Not a typical summer day - it was cloudy, rainy and windy, so instead of swimming and sunbathing, I took a camera for a walk.
I decided to warm-up the scene a bit, and so I used the gold/blue polarizer, which in combination with the graduated ND filter gave a very interesting colour to the dark clouds in the top of the frame. I know that it doesn't look realistic, but when did you see a 90 second exposure that does?

I cloned out the buoy that the boat was tied to, some dust specks, resized and sharpened and that's about it for postprocesing.

Comments, critique or faves are much appreciated!
