I wanted to do a sea-monster that delivered something other than a plesiosaur or the old legendary sea serpents. Playing with scale is a reliable way of delivering something that is both familiar yet fresh, so taking elements from frogs, turtles and Siamese fighting fish and then scaling them up (a lot) resulted in something i was really happy with.
The swimmers hopefully bring a friendly quality to the creature as they're not fleeing for their lives.
I've also included the original pencil sketch below as the line work was lost a little when adjusting he contrast for the sub-marine feel.
