Everyone has their hurdles. Just because he's not an actor doesn't mean he can't learn how to fix his facial expressions. Gauhar is a model/actress and her expressions aren't good as well so just because one is an actor doesn't mean that one is great with expressions. It needs work.
they should bring someone to teaching him acting, then bring him to the competition.. that how it works here in U.K. they assist the contestant to perfect what they lack.. like deepak taken parul for showing the dance form, that is the way you should teach them to learn.. i am with what Rahm says.. judges are biased towards baichung.. no doubt about it..
