shirt creasing and angle is off. The angle of the sleeve looks like the arm is extending away horizontally when it's mostly going down vertically.
left hand should protrude below the fish more
the way the hand looks, it's full closed, but that shouldn't be possible with the fish tail, so the hand should be a little more open.
I'd draw the suggestions, but I got work in 2 minutes.
