Have fun when you goes into the studio to record this. That riff that starts the song (and also ends the song), which I assume is the chorus/hook section is really good. It sounds really dark and ominous, sounds like something I would have used on my project. Do something exciting leading into this part. Maybe some drum fills right before, maybe the bassist can slide or the guitarist does a sick ass dive bomb (and switch things up so it isn't the same right before leading into each section but similar.) But you did a good job at the end when you went back to this section so it may need that type of flavor only once in the song.
I could tell the solo section wasn't ironed out yet, but it's so nice to hear more solos as a lot of the newer bands don't have songs with solos. When you do go into the studio cut the section I referred to earlier multiple times then switch and do overdubs with a different amp and in a slightly higher register just to accent some of the notes.
The bridge section before the solo was the only part I wasn't too sold on. Not because it wasn't good but because it didn't seem to fit the tone of the song to my ears. However, it would be great to hear a slow variation of that at the start of the song and then go into the section that you originally started the song with.
