Nice lead writing here, but your low mids and bass are heavy, muddy, and cluttered (chord wise)
I will say I REALLY don't like your guitar synth but that's just because it's machine-gun attacking. I would recommend something like RealEight, Ample Sound AGG, Shreddage... Or if you need a free library, Ample Sound AGML. The attacks on all of those instruments will not disappoint you.
This out of the way, 1:38, that lead has been waaaaay too loud for a bit and actually distracting me from what I was typing. It's a consistent problem throughout. It's glaring enough I think it could actually be your headphones not presenting to you in that frequency range. If you really can't hear it on any of your gear, I recommend Audio Technica M40x, used, if you can afford them. They are indispensable to me in identifying problem parts in the mix. Failing that, you can always look at a spectrum analyzer and/or sweep your track for frequencies that are sticking out in the mix with ReaEQ. If interested, PM me and I'll find the tutorial where I learned to do that.
You've structured your song well. However it does sound like it's been mixed way too loud before mastering FX were applied. Protip, before you apply FX to the master channel, make sure your track peaks no higher than about -6 dB. If your mix sounds good here, it's ready to be mastered. It's hard to squeeze a track under -6 dB when you're used to mixing everything all the way up, but it's worth it. Mixing loud will not make everything sound better unless it already sounds good.
4:01 I can tell this track is compressed way too hard with how loud that lead is. Headache territory.
I definitely recommend some tutorials on mixing, mastering, voice leading, and writing melody/chords. For the first two, you'll want to try to stay genre specific, but the last two, Ben Levin does some great instructionals on YT. As someone who's been reading music and studying theory for years, it helped get me out of a box.
I do see potential in you to be great. Can't wait to see how you grow over the years. Thanks for coming out to NGUAC! :)
