The god of the sea Picture

A piece based on Neptune/Poseidon, a kind of universal sea god image for my exam sketchbook.
At the moment I'm doing a bit of research into mythology for the project, and found out that the Greek Poseidon and the Roman Neptune are actually very simlar and have been given a lot of the same characteristics.
