I am a 16 Year old boy and from last 2 years I am trying to learn singing, I have good voice and I think that I have that kind of range(tenor) but not that much similar voice like him when I try to sing or sound like him. It sounds young still it is different from weeknd like it sounds like other artists. I watched many videos but didn't found that much useful. What exercises and vocal routine should I do. Do I still have time to change my voice????
