thank you!!!! any tips on how i can make her pose less stiff?

I cant really explain but maybe I can show?

Gimme a sec

Making the pose follow this flowing line makes the pose smoother and has more dynamic

It depends on what uou have in your vision while following the lines or making them.
For example This is what I had in my vision while adjusting the pose to the line

I lifted the left shoulder and sinked the left hip.
The stomach is going inward while the lower body and head are facing outward, makes the pose abit more interesting

I also repositioned the right arm and made the hair rest on the girls left shoulder so it looks more natural
