Brief answer and quick watch of the video because I'm on my phone, but 3 thing stand out immediately -
1. She needs to stay over the bar longer in the pull - to about mid to upper thigh.
2. She needs to stay flat footed longer in the pull.
3. She needs to pull under the bar w better mechanics to keep it closer, ie continue pushing it in and lift the elbows high and out.
Hope that helps.
