nice. this shows the downside of sand hybrids which is the color washout, but the form and size of the flowers on this one looks like it is quite a show.
Normally I would agree with the Angel hair guess. It certainly could be. But I have bloomed about 6 of paph Lefty Kei and two of them are the exact same as this one. The color, stance, petal length and width, everything. You would definitely think sanderianum x William Amber would come out darker, that is what I thought too. The other four were darker, but two had lighter color like this more from the sanderianum. I will try to find some pictures somewhere.
