I think there's too much muscle efforts to do this, it's definetly an hard song but I can feel you're taking big breaths and it's like I can't get the feelings through the vocals cuz I'm feeling the difficulty of it. I like the last part because it's less dynamic, it sounds better. I don't like the glottal sound, but this can just be my propsective, maybe you're doing it like she does, trying to get to that point. I'm womdering your own way how would it sound 😊
