She does an ok job getting down that pitch. (It's slomo which tends to smooth things out.) But expert bump skiing it is not.
Technical points I see is collapsing at the waist and lack of leg mobility are affecting ability to manage pressure, lacks steering and has difficulty controlling line. Her stance is too wide for bumps and she occasionally stems. The coordination of her movement patterns still developing.
Part of the upper body chaos and ensuing lower body late turn initiation is that her poles are too long for good bump skiing technique. She's getting knocked backseat by the long poles and arms are getting bounced up higher than we'd prefer in the bumps.
