Is my stromanthe doing well? How can I help her thrive?

It looks fine to me. Avoid direct sun and tap water, and don't let the soil dry out. They like humidity.

I’ve had her for about 3 weeks now in this window - I run a cool mist humidifier for 3-6 hours and mist her every morning. She has been watered deeply twice and seems to take a while to dry out. I’ve never had one and don’t know how to tell if they are thriving or barely hanging on.
