What you have here has some cool ideas, and is fitting based on the theme. I like the choice of synthwave and rock fused in too. Honestly reminded me of Expendabros or just some badass action movie. The heavy guitar works very well and the melodies sound good. My only big criticism is probably the mix and the sound of drums. I think the mix lacked some glue and punch. The drums sound very dead in the mix, the only part where the drums are more open to hear is the beginning with the synths and the parts where the guitar playing gets more subtle and quieter. I think its because as soon as the song builds up there are a lot more layers like the guitar that are super loud that overpower the drums. There was a point where i could barely hear the snare around a minute in, believe it was the breakdown. I think what could fix this is probably adding some compression to the drums and definitely bring them up in the mix. Make the kick a little more boomy, MAYBE change the snare to a different one that has little more decay and ring to it to match with the rock-yness vibe of the song because the snare was probably the most dead sounding in the mix, and i don't mean dead as in a bad way at all, its just a way of describing a snare that hasn't got too much punch to it. Essentially, try using a drum bus to bring more out of the drum sound and then in the master EQ a little bit of the highs to have the hi-hats stick out more with air though maintaining the harsh frequencies and definitely bring out more lows too because when the guitar comes in the bass is almost not even there lol, and you know when you got a song like this one, you're gonna need some awesome bass in there (despite there being the synth bass but i mean more where the guitar part is heaviest). Finally, make sure everything is balanced and leveled using the ears. Overall bro, song is good, and has some great potential with the melodies and just the feeling of it in general, just work on the mixing a little bit, try experimenting more with compression on drums and the master and you'll get there. Don’t know what sound references you’re using but best to use some monitors if ya can afford them ;)
