As these other people have stated it's not a question that can be answered in written text. Only listening to the mix and adjusting the mix will expose the propler level for the vocal track.
However there are a few tricks you can do use to help answer that question if you don't have an experience engineer to play your mixes for.
1. Go listen to your mix in 3 different places outside your house.
A. In your car
B. In your car while driving. Road noise can change things in this listening environment
C. In your office building at your desk
D. Through your
church PA if you have one
E. Through the PA in a bands practice room
F. Take your mix to a local music store that sells recording gear and audition your mix through
multiple other reference monitors
When you do this I highly recommend taking some notes on what you hear in each environment. That way you
can reference those notes when you get back to your studio and make the adjustments you think are appropriate.
The last suggestion I'll make is one that you can use mixing any thing to get a perspective on. Of course the above
examples you can use this way as well. Play your mix against a popular song in the same genre mixed by a pro.
This will give you an idea of what the pro thinks about it but it's not law of course.
I hope this helps.
