I agree with littlefrog, I would prefer it with a more upright dorsal, but if it's only just opened it may still stand straighter... my Maudiae looked similar when it first opened, but stood straigher a few days later.
Mine of this sort of colouring opened REALLY slowly. Took a long time before it was fully open. On the up side it seems to have a good life on the flower, it's been open a month tommorow and is showing no sign of aging.
