I based the top piece on the comics at that time. I was laughed at by other artists at work and I was told the idea of Aquaman with a hook hand was terrible. Eventually the same artists/producers that gave me a hard time were responsible for the Aquaman episode on the Justice League show that features the origin where he looses his hand.
Years later I was asked by a WB producer to do the top piece. I made it for a fanzine cover back in 2002.
