That is beautiful. I like the yellow shades on that flower.
I have the exact same plant (even same award) but the flowers were white, with green shades instead of yellow. The patterns are all identical - even the stripe along the petals. Just different colors.
I wonder if it was due to lack of light or I happen to have an alba variation.
The color form that you have is actually what I was expecting from my plant.
This is what I had.
