I think your vocal sounds fine. I did not find it to be nasal by any means. In fact, your voice sounds perfect for this genre. By the way, I've subscribed to your channel, liked, as well as commented on your video (my YouTube name is Prawol Bhattarai). Also, I think your lyric video looks great and I was curious how you made this video. I'm a big fan of lyric videos myself and would love to make something similar in the future. Cheers!!
