It's actually quite a nice flower. Good size, flat dorsal and awesome color.
I do see a couple issues for this flower (which can improve greatly in next flowering):
1. petals are a little narrow and not mirror images of each other
2. the pouch looks a little indented at bottom on the observer right (flower left) ...maybe camera angle?
I think the synsepal width is good and it was the pouch that threw it off. Maybe show a pic from back?
I am sure on the next flowering it will be rewarded nicely. Keep up the good job.
