First off I applaud you on a great song selection Bon Jovi is one of my biggest influences.That being said I'm no expert and I mean no offense but it sounds like you are straining your voice quite a bit.Before you seriously damage your vocals I suggest finding your vocal range and staying within the bounds.It's ok to push the envelope I think most everyone does at some point but just as friendly advice I would hate to see you loose what you have going.I think you have a great voice best wishes R.R.
ITS ALSO MY LIFE FRIEND,I GUESS PEOPLE HERE IN RED SHARE THE SAME LIFE,MUSIC,MUSIC,MUSIC....

Keep tryin' to get your voice in vocal ranges. I liked it a lot.
