My only complaint is that she looks too BBC. Stand her between Laura Kuenssberg and Emily Maitlis and spot the odd one out. That and every youtube video I've found of her has her acting far too restrained to be the doctor.
That said, she has enough time to fix that, I look forward to seeing her be anything but normal and restrained.
P.S. She's still playing a male timelord, just temporarily in a female body. Same way the general was always female.
