You can tell its fake if you ask me. Of course, I knew it was fake going in... but the face put on top seems slightly angled.. looking at it straight on, it seems the left side is pushed back a little, like it was a flat plane, and someone just tipped it slightly. so his/her right side of the face seems pushed in.
this is kinda scary tho, imagine what damage things like this can have. if it can be faked without anyone knowing it. u could literally make any public or private person say or do anything especially as things get more and more realistic over time.
