I like these songs. Your voice is lovely. The piano parts are nice. Your melodies are great.
There are a lot of parts that sound like you're compensating for lack of a band. Particularly in Bells. If you had a band, the piano parts wouldn't need to be as focused on displaying the rhythm, and could instead be providing more melodies and interesting harmonies.
The songs also give a bit of an impression of all being a bit too similar. I suspect that impression would go away a bit if they had more arrangement.
My opinion of the lyrics fell after listening to the songs about three times each. There are a gazillion teenage girls singing vaguely poetic things which sound similar to you. (Note that some of those teenage girls manage to be successful anyway…)
