Just an observation:
The actor seems to have better emotional depth on his expression when he is not actually facing the girl.
Like the lift scene;
Bad me bataunga scene..when he stands alone in the hallway just recollecting himself..
Dupatta scene...where he puts it on to her from behind
I think when they face each other he becomes a lil conscious and tries to overcome it and it kind of shows.The lady on the other hand puts up better expressions when actually facing him.
Her best so far has been the one in which she tells him she would have fallen in love with him.Her gaze was so direct and intense.He did good too in that!Especially when she mentions the bet.
The sweetest moment would be when both say hi to each other at the dandiya.Armaan says it again wanting her to look at him while greeting him.That was cute!
