oh yeah! he shows such amazing variations in his voice! loved how he growled "how dare you?" when he grabbed aastha during their fight after carom match. he changes his voice even in the emotional scenes, like his throat is closed and he cannot speak normally. he is an amazing actor. he pays attention to these finer details.
but there is always scope for improvement. he should concentrate on learning accents of people with various lifestyles. It would help him.
