It doesn't hurt, and I'm learning about a year and half right now. But only now I bought a microphone, and started to record, listen, analyse how do I do it and trying to make it better. At first I didn't wanted to do cleans at all, but thought I could try to put some scream with the clean voice. The sound was "interesting" (for me) and I decided to leave it in track. About the second thing, I didn't understand, you are talking about my vocal, or is it in the song vox? Thanks for comment!
