While searching for a suitable underwater background for a mermaid lineart I'll be working on later, I came upon some pictures of people known as "Sea Gypsies". They live in the tropical regions of Borneo, Thailand, and other parts of southeast Asia, in houses built on tall stilts. They learn to swim at a very early age - almost at birth - so they can master their breath control and heart rate as they hunt underwater for fish and other seafood. That's what made me think of this drawing of a cat hunting underwater for a tasty meal. After all, what better animal than a cat to hunt for a fish?

The fishes are linearts from an old "page-a-day" calendar I've had for years.
The rest was done by freehand.
Hope you like it!
