Hmmmm..... soothing. But not enough.
Very good. A nice start to a song, but, one problem being, its just an extremely long introduction for a song you haven't made yet. I understand its a draft, but the song sounds very repetitve, even when you throw in change. If you take this, shorten it, and make it lead to a triumphant climax, then it will be perfect. By "triumphant climax", I do not mean to say that you should take such good sound, and ruin it by making it just like some of the fast-paced, obnoxiously loud trash you can find anywhere, in the Portal or on shelves, if you close enough. What I mean to say is, this draft is very soothing and calm throughout its whole playthrough, and it should not be. There should be something in here that does not just make me have neutral, emotionally-numb feelings, but add something both beautiful, and wonderful, if you know the difference.
