good. the volume of the melody is too high, also if you put a sub bass, or a generic bass, i'd suggest to add an equalizer to the melody and remove the basses, cause you already have them in another instrument.
also, i really like the arp, but it's always the same, and there is no main melody which usually is what makes a song amazing or just good.
anyway, i like the way you made the basses, the buildups are well made, the arp too.
4/5 stars :3
