Its a melody, lol
Very nice melody. But, before you throw it into a full length song (which I wold be interested in hearing, by the way) make the melody longer, and expand on those high notes, and make sure that the delay isn't fighting for sound space =) Give the delay some room to breathe.
Nice, but please try to only submit things that are either finished, or can be used in flashes =D
Keep it up!
