Turns out one of my characters actually has a job! Wendy works as a diver, unique that she can do her own commentary. Plus, she's an excellent swimmer, and her suit costs the aquarium much less than scuba gear.
Her stripes are artificial; she's naturally that sort of dull orange and figured she'd get some tattoo-equivalents and call herself a tiger shark (she's not).


Her head's supposed to be flatter, but I can't draw that consistently yet. Similarly, those fish definitely have an artificial reef and other stuff in the tank, but I didn't sketch it and an nowhere near confident enough with a felt-tip yet.
