Those are just too good, I would not presume to critique, but I will say that I like #2 the best.

I like #3. It has a surreal feel to it and it takes a bit of effort to work out what it is.

My vote is for #1. It would be a brilliant cover for a book or poem about a ghost ship. Bright but haunting. A great composition, too, which must take practice when you're effectively framing upside down.
Cheers,
Rick
