I am utterly aghast you criticize your voice at all. I think it's crisp, clean, and refreshingly natural.
Also amazed you mixed this on apple earphones. I also have tinnitus so I sympathize with mixing with one's eyes LOL. I constantly hear cicadas, crickets, whining computer parts, and TV static that isn't really there. It's a challenge to cut through that. Sometimes sounds like I'm listening to the world through a drink straw.
Only mix critique I have is that vocals be bumped up a dB or two, and hihats and cymbals conversely come down a wee bit. Beyond that, this is about as perfect for me as it gets. Perhaps the open close hi-hat could move a bit to the left channel, 5 percent or so, with room overhead emphasized in the right, if applicable. I also can't hear toms too well, perhaps .4 dB boost or less would do the trick there.
I feel your automations of FX serve your phrasing really well, and the choice of Battery with previously recorded samples was a genius idea.
Also, glad to have surprised you with my true nature LOL. I'm a goof with resting bitch face in the nth degree, and I like to make weird faces.
