I loved this song, everything except the weird mouth bit in the middle, I was feeling it, I was into it and that just ripped me away from the moment where I was enjoying good music.
If the band insists on keeping it, bury it under a ton of reverb so it works as texture in the background.
The intro isn't quite there yet, I liked the vibe you were going for but I think it would work better if you added some reverb/delay to the vocals, make it feel like they're singing at the top of a mountain.
Otherwise I think this is great, just listening on headphones so I'm not sure about the bass, I'll take another listen to it when I get home. Good work.
