Great vocal delivery! The tone of your voice is totally appropriate for the genre and the lyrics are fitting. A minor thing regarding text setting - putting the emphasis on 'is' in 'this IS fareWELL' in the chorus is a little awkward. Typically you'd try to write the melody so more important words get the stronger beat. Instead of starting that line on the pickup so 'is' starts on the downbeat, I'd try doing 'THIS is FARE-WELL". It's the difference between <and ONE two-THREE> and <ONE and TWO-THREE>. It's not a deal breaker and there are examples all over rock of awkward lyrical placement (Green Day's use of the world 'mel-O-dra-MA-tic' in Basket Case instead of how you'd actually say it 'MEL-o-dra-MA-tic' has always bothered me in particular).
The guitar needs to be WAY more beefy in the mix. It's pretty subdued right now. I can sort of hear what you're going for, but it lacks the punch I'd expect in this sort of alterna-rock track. I'd try rolling the bass off of the rhythm guitars a bit and let the bass guitar take care of that. Maybe double track the rhythm guitar and hard pan them left and right. Also, adding a SUPER short reverb to the guitars will help beef them up in the mix. If you tracked the guitars using dynamic mics, maybe try a stereo pair of small diaphram condensors?
The track looks pretty heavily compressed, but you have tons of headroom across the board. Was the limiter set a bit to high? I don't think you necessarily need to normalize it to get that brick wall, but because you have so much headroom, you probably could have squashed the track less and let some peaks pop through the texture. This may have helped with
3:45 - The guitar palm mutes/bass/bass drum are fighting each other pretty hard here. Try to notch out places for each of the instruments in the mix. They don't all need to occupy, say, 150hz. Really only one instrument is needed there at a time, the rest will fill in the illusion that they also live there.
All in all, really nice writing. The song is fun, energetic, and has that 'Foo Fighters' aesthetic you were going for. I'd book up on some mixing tutorials to get your ideas to really sparkle.
