i think it might have just as much to do with the fact an anthro shark simply makes no sense
unless you make their limbs their fins in which case they just look hilarious
Sometimes I think people tend to overdecorate their Sea-anthro with unecessary fins. "LETS PUT A FIN HERE AND THERE AND AND UHH"

There isn't much too it besides the frustrating part with the snouts and maybe the proportioning. This is one of my worst tbh. I've found that furry/scalie communities make tails ridiculously long sometimes. I chose to keep her tail short. Fur bothers me more than anything and I remember reading a book where there were anthro alien sharks.
