Sounds very nice - I love that type of slightly trembly chick voice... and everything seems to fit well. I'm only listening on small headphones via the work PC though, so not getting the full detail.
Song-wise I didn't think the repeated echoey lines worked, or not for me anyway, I was expecting the chorus at that point - and I think the third one needs to come forward a little, it sounded a bit quieter than the first two.
Apart from that, all good. Nice work.
