Soooo you asked for harshness... I'm gonna be harsh.
At least i'll try.
And that's not easy. Because it's great, actually.
The harp sounds a bit weird on the highest notes and overall it lacks maybe some EQing ? I don't exactly know what's wrong but it bother me a bit.
The harshest thing I can say is that I personally think that the 5 stages of grief isn't a great subject - but it's my scientist side speaking (this model is largely untrue and were deviated from their original meaning) so I don't like that but it's personal. Your story is beautiful despite this.
Your voice track isn't very clean, you lack an anti-pop filter! Idk if you tried to correct it afterwards but if not, a low cut filter would have done most of the trick. Aside from that, your voice is goddamn beautiful, I love it.
Overall your composition is beautiful. You have great ideas, well executed. Your songs are diverse but coherent, it's perfectly balanced. It's I think more on the production side that you need to progress but you're on the right (sound)track. Very nice submission.
OH, ALSO : Very nice Ableton layout.
