Its beautiful. pretty much all the scales needed, and blends 2 together. (Final Fantasy Scale probs a bit too far X]) u can transpose AND change sustainability. Im not a very good keyboardist myself, but i play guitar and write music so i can see this for what it is meant to be. Well Done.
Only Thing i can suggest is add a variety of tones???
Oh and Hats off for Mentioning Jordan Rudess. DT fukkin rule m8 !!!!
