Ok constructive critisism.
Ok first thing is the levels are wrong, and your doing a repetitive basic tune that I was learning In preliminary piano. BUT iff this is only the "demo" then I look forward to the rest but I can't give this a high rating sorry man. I think you should stick with this for the intro but whatever makes you happy. Im giving you two only because this could end up being realy good but "maybe". Good Luck.
