@silentheart00 nice work, but there are some visible anatomy mistakes.
1. Sternocleidomastoid muscle should go from sternum and clavicle to place right behind the ear, not behind the neck.
2. Chin profile should not be the same as jaw profile because of suprahyoid muscles.
3. The clavicle is too straight in my opinion, it should be more like a cupid’s bow.
That’s just my observation though, not like I’m an anatomy expert or something.
