Thanks for the offer mate, but I think I’ll pass. I normally don’t make a habit of handing around my MIDI files, I’m sure you understand that. 
Personally, I don’t think Pianoteq is any competition for Alicia Keys Piano. The tone I know is mesmerizing, it’s a Yamaha C3 Neo, great rich piano with only 3 of them still in existence I believe. The Yamaha C7 is the more brilliant piano, and more suited for rock songs, but I’ll certainly agree, the C3 does have nuance.
I’ll be sending the song to iMix and Master today or tomorrow hopefully. I’ll show you the final results.
A special thank you to Bassbase, Shadowfax, and Foolomon for your advice. I owe each of you a favor.
