Hey man, thanks for sharing!
The Demon I Know
-Lead vocals can come up for sure. While I can hear them, and mostly make out the lyrics, they feel very distant. Try pushing the fader up 2db or so to start, and once they're a little more out front, you may need to deal with compression, but they sound very compressed as it is, so probably not. Right now the most powerful instrument in the song is the snare, and you definitely want to vocal more prominent than the snare.
-Kick is really powerful and punchy. I like it.
-Overheads are very wide, as another poster commented. Bring those in with some stereo narrowing or splitting and panning yourself (as suggested above).
-The pre-chorus breakdown around 2:00 sounds very empty and boring. It feels like there was supposed to be something else going on there and you forgot to un-mute it. Take another look.
-Bass is lacking. That's become standard in modern rock mixes, but I prefer a fuller low end.
-Chorus guitars are big and powerful, very nice.
In The Shadow
-Rhythm guitars are awesome, as are the chorus power guitars
-Ambiance of the entire song is really nice
-Same comment on voice as above, it feels distant.
We Are The Ones
-Same deal with lead vocals
