Update on the Mobian Shark 3D Model

New update of my work in progress of a Mobian Shark's body. I did some research on the actual shark's anatomy such as the shape of its tail fin, dorsal fin (for the back body), and pectoral fins (on both arms). I created the pectoral fins on both arms and the tail fin by extruding the faces and forming the shapes on each part of the model, but not the dorsal fin. It's coming along nicely and there is a lot of work. Here are the images of the body model shown below:
