Here I am Aravind. Well I am quite new to this forum so I don't know how your singing was before this cover.....my ears were pleased by your interpretation and your vocal emission but I think this key now is not the best for you: the high notes are a little forced so maybe to get a perfect cover you should change key (1 o 2 semitones down) till your technique allows you to reach them seamlessly. By the way It's a good job, really a good one......well done!!
