Well it sounds pretty good so far, nice melody, white noise could use a little less highend, chord progression is good, maybe a little more variation, same with the melody. A pretty good start for the beginning of the song. Perhaps on the second melody pattern, or when the melody starts again you can have it continue to ascend, instead of it just going back down. Just going with what I hear in my head, good luck, and I hope to hear more of this track.
