The neck is kinda off in the first second and 25 seconds in and seems to spill over the collar unnaturally, and the head seems too big. But otherwise very convincing. If someone did not tell me it was fake, I probably would not have noticed.
Yes, same here, once I knew it was a fake I started looking and the head looks glued on... without the tip, I might have unconsciously notice something was off, but would not be able to put my finger on it.
