how about a gradient with dark blue to white, like it's deep under the ocean? also, i feel like it needs a little more. a shark? a treasure chest on the opposite side?
I like. The blue is a better colour choice and the sharks as well all contribute to it looking deep under water. But the mast looks very stumpy. It really doesn't look like there'd be room for the sails to unfurl.
Really cool idea. I think the mast could be even taller still (or jagged on the top so it looks broken off) and the light rays could use some fadeouts on the white edge so it doesn't look so harsh. I love the sharks!
