Technicals: great control of the sky. full props for that. I like the composition as well. Focus is sharp.
The feel: I think it is very tricky to pull off objects that are almost sillouetted, but not quite. If you are going to have detail, I'd wish it was on the "pirate". That figure seems a bit lost as a sillouette in all the rigging.
The game: Ships seem to do well on DPC and I do think your sky was excellent.
I like that there is detail in the sky, but the highlights are too bright for the rest of the silhouette look to it. If having a more low key shot, I would like to see throughout and may bring out more detail in the rest of the awesome wood of the boat.
