Sorry I am not following. I don't think that is very disappointing. I like the almost white dorsal, the greenish petals and the spots look dark on the petals. If its disappointing because it only has two flowers or something, it is two more flowers on a stonei than I have blooming. You should enjoy and it should be better in the future.
I know how it feels! Generally stonei flowers are quite pale and doesn't compare to rothschildianum. Your flowers are quite nice and quite colorful. I was disappointed with the color of my stonei as well and it was not up to my standards!
