try to keep the leading leg straight at the contact pose, also toes up and in the back leg heel a bit up.
You may need to move whole body up to straighten the legs.
You can also try to softer the arm movement as they swing unnaturaly and unfemine.
Also the head nodding during each step is unnatural.
if the rig allows you to move the braid, use it
Thanks for the comment
And the suggestions
As for the head yeah it was to much
