For a unfinished song this has some really well done ideas and bases to build upon, that being said I feel as though some of the clean sections left me wanting something more done with them as they felt either to long or could have something done over top of them, like a guitar melody or something.
Riff wise there was some real great stuff here that I really enjoyed that worked well with the leads and some other stuff felt a little bit to filler, like it was there just to make the song longer for the sake of a long song, some riff dragged, some riffs were pretty awesome especially at about the 4 min mark, loved the chord usage.
overall, it was a enjoyable song and I am excited to see where it goes from here.
A solid 4/5
