Congratulations on your PRs.
You open up a little better on the first one but keep in mind, when your attempting PRs the technique is most likely not going to be perfect. The speed under the bar is fine. Just remember to actively pull yourself under and maintain tension on the bar.
You're a bit shaky in the bottom position but again, things like that are expected when you're attempting PRs.
Other than that those are great lifts. Good job!
