I'm not the greatest metal fan, but I've listened to some metal tracks and went to a metal concert last year.
What you should improve is the mix. I mainly hear the chord guitar playing its chords. What I would like to hear more is the other guitar with the riffs (or however to call it - as I said before, I'm not an expert in this genre).
The song has too dominant highs and too weak lows (maybe it's because I listened the song on my laptop), but try to improve it, that it sounds great on any device ;)
good too short and need a little something something in it . it feels like something is missing and yes like daniel said the mix, work those levels a bit oh and double the track length at least
