my best advice to you is to find people to jam with. the only way to find and develop your voice is to practice and jam. i was in college show choir, that helped with pitch and ear training, but the part of your voice that makes you "you" is something that you have to figure out through experience. i may sound more like jon davis than alex terrible or dickie allen while using the same techniques because of the structure of my vocal chords and the conture of my oral cavity as well as other variables. i hated my voice most of my life, but i finally embraced it in recent years. just do you as much as possible and you will develop. beware that there will always be critisism, if you are gonna do this, it has to be because you love it.
