I realize it's a demo
but make sure when it's good and done you've worked out some issues with production.
right now it sounds like a one-track recording. Volume levels are haywire and it sounds very jumbled. I also realize how hard it is to get a good drum recording but it's very crucial as a foundation for the piece.
musically it has potential but make sure everything is together rhythmically or else it will detract from the cool melody going on.
