What a beautiful bird!!! I am throwing out a few things off the top of my head so wait for the experts to chime in. I see Yellowface II because it has gone into the wings as well. I would think a pied of some sort although I do not see a variation in color on the stomach. Judging by the cere if it is pinky purple like it looks I think it rules out Dom Pied and leaves recessive pied or maybe clearflight(Not sure if CF have a pink cere).
