it looks good, except the face is still far to flat, there's tuns of triangles and the edge loops are all over the place. Start again on the head,use fount/side refarance images and structure the mesh simmaler to image above. That mesh would be very dificult to UV unwrap. the section under the armpit from the side view also needs some atension, this wouldn't animate very well..
hearses anouther model for example, its not human, but isn't that different in terms of mesh structure, the main deliverance is i redirected some edge loops to form the pointy chin. these would normally go around under the mouth.
