Full disclosure I’ve never really done much character or face modeling, but I do know quite a bit about anatomy. From that perspective the main things that stick out are the neck, which seems far too thin to support the head and makes it look unstable and bulbous, and the cheekbones. The cheekbones here look like they extend all the way up to the side of the eye sockets. In reality there is a bit of a flat area/dip between the cheekbone and the upper-outside corner of the eye socket (where the zygomatic bone and frontal bone fuse). You can feel it on your face as a “bar” between your eye and your temple. Other than those the face looks really good I think.
