check out my no music cover how is my voice listen to both my classical music teacher helped me prepare for it https://www.soundclick.com/artist/6/aankhen_music.htm
it was nice.. but u tried very hard to get vibratio in ur voice... i got an advice.. instead of singing direct from mouth.. try singing with ur throat..
piya sounds like that cuz i recorded over the original song cuz i cant play the guitar that well and i need the music thats why most of my songs are without music thanx for the compliment though
