From my view the nostrils are too wide and not flared enough. The ears are slightly too low. I think the comparison makes them look way too low because of the slightly different angle. The real Hemmy's head is tilted down more than the Hot Toys' head. The jawline is a little too broad. And the eyebrows are too furrowed for my liking.
It's a decent likeness that needs some adjustment. I still think it's worth picking up.
