OK the backing track is getting there this sounding much better.
What are you doing to the VOX? its slipping from channel to channel here do you have some sort of widening on it. If you do back off on the depth of the widening.
Not wishing to teach you to suck eggs, but on the subject of reverb here is how I apply an overall mix reverb.
1. Solo each track that has reverb
2. start at zero send to reverb bus, apply that send level until you can hear it then back it off until it just disappears from your hearing.
3. Then with all tracks live adjust individual track reverb sends until it sounds right.
For individual track inserts remember to balance the mix or wet dry levels and listen with the overall reverb, if applied, as reverb can get messy very quickly.
An overall mix reverb will help create an overall sense of space for all the parts to sit in.
