The compressor...

You might have intended for the compressor to kick out some of the instruments as a result of the bass, but it might be too compressed. It's really noticable when the strings are playing, which I would have excused if not for the fact that I can hear its effects on the piano too. Actually, better idea: lower the volume of the kick drum. With its volume level, it won't drop the actual volume of the kick, it'll just lessen the effects of the compressor.

Another thing: you might want to make the release longer on the strings or add some reverb. (I recommend both, but if you're going to do only one of them, do the first one.)

Other than that, this song is pretty good, it's nice and chill. The melody, as you say, is pretty catchy. Good choice of instruments too. I really enjoyed this song, good job. It's too bad I can only give you a 7/10 because of what I mentioned above though, which really isn't bad btw.
