I listened to mix 6. You've completely eliminated all the bass in your voice now.
This is a big bottom line here for me Master, and you may not like it, but if you can't hear that adjusting the eq thinned out your vocals to that extent, then maybe this isn't the hobby for you.
Maybe you could focus on recording technique, then get someone to do the mixing for you?
Straight vocal onto a backing track wouldn't even be all that expensive to have mixed professionally.
See, to me, rather than manipulating settings for a while to get what you want, you're letting us hear every little adjustment to see if we like it.
That's not really a healthy method man, because every recording scenario is different and you're not really going to learn anything that's usable in the long term.
No one would expect you to get it perfect straight off, but an eq is one of the more straight forward things to work with.
You should be able to just grab things and move them and ascertain whether or not the result is good, to you.
