This was actually one of my wife's amazing suggestions - "A samurai sharkman with a goldfish friend as a necklace" - I tried my best. I love sharks anyways (I mean, I named my studio after them) I looked at Halo's Elites for his posture as I didnt want to just draw a human with a shark head but I forgot his tail! I may draw this guy again and add that in.
I enjoyed building a backstory for this guy so I added all sorts of trinkets and charms and a hodgepodge of gear to make him look like his armor has been pieced together as he sees fit over time. His Goldfish i purposely made bug-eyed and cute looking to contrast the fierce shark face, which I based his colors and face off a real picture of a Sand Tiger Shark. I love their golden-greenish yellow eyes and horribly menacing snaggletooth mouths with teeth jutting out everywhere haphazardly.
