Sandra,

As stated by many above you are already ahead of the curve, especially with phrasing, which in my humble opinion, other than staying on key is the most important part of any vocal. Heck phrasing is also, again in my ears anyway, is what separates many musicians from the pack even with instrumentals. With this said my first choice would be for you to go for it and with the help of your vocal coach do the vocals 100% yourself. Second choice, and only if you are not yet comfortable carrying the vocals yourself, would be to use another singer but also include your own vocals even if in some minor way as a duet or in a background role for starters.

But the bottom line is that you and only you can make that decision.

Break A Leg!
