If you ask me, it's not very creepy. I know it's just a pencil drawing right now, but it's hard to give a pencil drawing the creepy look to it. Especially with no colors. It's a cruise ship, just not a scary one. I think the creepiness of a ship would increace by alot if you had a dark backround.
One thing you can do is to not have any lights on the ship. Make all windows and lights that should work (which would make it look non-creepy) and turn them off.
