New to this type of begonia

I have a polka dot begonia and its structure is entirely different.

The one in the photo I have under a grow light in my bathroom. Where I hope it receives the humidity it prefers. (Ill close the door after showers to boost the moisture)
Its experiencing some leaves drooping but its also flowering?

Is she in shock from transplant?
Is this normal for the larger leaves to do this?

How do I know if what im seeing isnt a slow death because of my own ignorance. 😮‍💨
