What next?

I adopted this girl from a friend a week ago who was killing her. Lots of dead leaves, too big of a pot, bad soil etc. I transplanted her in a smaller pot after pruning dead roots, leaves and used special Calathea soil…plus put her in appropriate light and humidity.
A few of the leaves are curled in and a couple turning brown. I feel like I e done everything I can think of. Not sure if she’ll live, but is there anything else I should do?
