Listening to Track #1 right now. It's beautiful. It actually like that it's more soft and not too strong. It sounds more delicate. I absolutely love it, congrats.
Track #2, you have a very good voice, but it sounds to me that you have a bit of trouble with the higher notes, they sound somewhat weak here and there. Very good entrance though, good job.
Track #3, I can't honestly say that you suit that song too much, because most of the time the music is covering you up. Next time you record, try to play with the volume so we can at least hear you. The higher notes seem to be a problem for you as well, your voice practically dies out. Not bad, but I think you could do well with a bit more practice, to strengthen your vocal cords.
Track #4, I don't have much to comment. You have a pleasant voice, you were on key most of the time, very good entry overall.
Track #5, I don't think you suit the song that well, and you should make use of your chest voice as well, because it sounds to me that you're using only your head voice throughout the entire song, even in passages that could use a lot more strength that the gentle tone of your head voice can offer.
Although all entries were good, my vote goes to #1. *sends lots of <3333 her way*
