Interesting effect. You have really gone outside of the box by using a model ship and by creating the illusion of sailing. I would prefer a slight more cropping on the left, just to complete the composition.
Hmm. Looks too much like smoke swirling around a toy boat. The illusion might have worked better with the boat in water or somehow appearing to be in water. That said, lighting is kind of fun and it's a very cool toy boat.
"A" for effort, but... The scale of the smoke pretending to mist kind of does not work for me. The lighting also is unreal and obvously there is no water.
