You have an amazing sense of progression, and your chords are wonderful. I feel like I could learn a thing or two from you. Your guitar and piano are well played, and the drums are tasteful and minimalist. I already get the sense of staring out to a window.
I have no complaints about mixing.
A few pickles:
1) For words involving ripping one's flesh etc., more expression is due. A guitar riff? A crescendo in general? Emptiness can be expressed, but those lyrics sound edgy, angry, and need the anger to couple it.
2) I have to agree with alternativesolution on your enunciation. It sounds muddled and dragged through. Clarity could heighten the feelings this piece is trying to convey. If in doubt, try overpronouncing your syllables. Don't do so too close to the mic, but try regardless -- with changes in volume where needed. And perhaps, you'll find a world of difference.
3) The lyrics are generally well-written, but could use tweaking in places.
All in all, pretty solid, even with its kinks.
6.9/10.
