Nicely done i really liked this
Wow I really liked this, and so did my speakers, the only suggestion I would make, would be to turn the melodies volume down just a tad, turn your beats up a little more just to give it that oomph, the bass on this was awesome and I loved those melodies, I think those suggestions would be the only ones I can think of for you for when you plan to take this beyond being a demo
all in all this was really good!
Peace Out!
