so i like the iron maiden vibes on this, your rhythm guitar playing is really tight and the solos are fantastic. the way the song takes a journey through different tempos is neat. i don't think your vocals have quite the right sound for this kind of song but your tone of voice and inflection still have this cool garage rock feel, and the scream at the end is siiick.
the drum mixing is super weird! the kick and snare are perfect for the 80s fantasy hair metal sound but they dont pop out of the mix as much as they should. the cymbals disappear under the guitars and it sounds like the toms have been muted and we're only hearing the reverb bus. the guitar solos are great but the washy reverb makes the tone feel less vibrant and accentuates the midrange in a weird way. idk if you multi-tracked the vocals or not but they feel like they've been stretched out a bit, like there's been a really fast delay effect added to them. the vocals are also just not loud enough - they need to be as loud as that guitar solo because they are just as important!
as far as the composition goes there isn't too much to complain about. the intro is definitely bloated, could probably just start on the first drum hit at 0:50. the transition from the slower breakdown section is cool but takes way too long to get to the point - like ok i get it the tempo is getting faster haha. the payoff for all that building up is just a weird sounding tom fill straight into the solo and you probably could've gone straight into that 16 bars earlier without the gradual tempo thing. also the fadeout ending seems lazy but it seems like you know that already.
anyway despite the criticisms i think this is a cool song with a lot of potential, and i'm glad you were able to get something in even though you didn't have much time. keep it up!
