This one's tough. The instrumentation is lovely, and at certain points, particularly when the singer drops into a lower range, the vocals work very well--for example, the latter part of Japanese bridge.
I think the problem may be that for the majority of the track, the singer is singing far outside of her range, leading to a strained, monotonous quality that desperately tries to hit notes, rather than evocatively explore them. As Monobrow said, there is a lack of control of the voice at these points. It is a bit harsh on the ears.
Cheers for the singer's effort and courage. Hopefully you continue to practice and gain control over your voice, as you would any instrument.
