Theirs

Reason is, ours looks more like Nosferatu and its scarier which is what Nosferatu is suppose to be; scary.

Also, the Japanese version of Volibear's Thunder Lord has a mistake where is lips are.

Its suppose to be black lips. Bears don't usually have pink lips. Humans don't typically have skin-pink lips, they're usually darker than what's on the inside of our mouths.
