Well firstly it sounds really nice, the piano noodling fits well into the song, good pop potential but it's dull as an instrumental, nice for the background but you should work on lyrics to fit the melody, it needs it. It makes me think of rain, bring that in maybe. I'm not keen on what you do at the end, I hear you trying to build to a crescendo but the vibrating guitar? I don't know what you call it and the drum just sound messy, I think they're out of time. Maybe just change the key up a step or two, it'd fit well in this style.
