I am flattered with Hemachandra's performance. I see many reasons for him to move to the top. Some of them as follows:
1) Very Good Voice Quality
2) Achieved Greencard on first performance of his every episode.
3) Diction problem vanished immediately after pointed out by Mentors.
4) Balanced way of Singing
5) No excitement / over action on stage like talking too much or crying for everything
6) Visibility of Southern Classical & Hindustani classical base
7) Appreciated by every judge and mentor.
I welcome your opinion on the above points.
My vote is for this guy only. JAIHO !!!
