This is absolutely fantastic! I love the perspective and light, as well as the excellent detail. A ship is not a place you'd expect to see a cat - and with the low POV you made her(or him?) look like a pirate captain.
Oh? Hmm... Maybe it was on another ship. But there was a couple or few years back of a ship's cat, I thought it was with the Kalmar Nyckel that was unfortunately run over. It was a cat that liked to venture into each port the ship it was with came into. Sad story.
I do like the idea of Ship's Cat though. I have a cat myself, named Magellan, he's quite the explorer. Have had him at a couple events and even camping. He doesn't mind the cannon fire or water. As a Pirate Portrayer, I steer away from a parrot or monkey. Give me the ship's cat!
