Paphiopedilum flower wilting before opening?

[UsagiGreenPaw]

I've had this orchid for about a month, currently sitting in a NE window in the PNW US area, zone 8b. Temps in house are generally 65-75, humidity around 55.

The flower on this orchid looks much less happy than it did when I first bought it. It looks a little wilted.

A couple of things. The door nearby was left open during the night because it was way too hot for sleeping and I'm sure the temperature dipped quite a bit. Also, I turned the humidifier off since I have such a hard time getting the orchid area warmer than 70%. It's the only window and it's the sliding glass doors to the apartment patio.

So, any idea on the flower and if I can perk it back up?
I was told this one prefers some shade, but I'm not sure a NE window isnt too much shade. Or is it the drop in humidity or temperature? All?

Thank you.
