Well, it's actually an electric piano, but I see places I could have made it sound more like an EP. My uncle is the top jazz pianist in New Mexico, so I listen to his stuff a bit. I also like Frank Klepacki and most any song that is well orchestrated or has a good keyboard solo in it.
And yeah, I have callouses on the Back of my fingers where I do those runs. When I get on a harder-keyed keyboard or piano I have to watch myself because I have ripped up my fingers before.
