A few PR attempts - C&J and snatch. Any tech advice appreciated

Attempted to PR C&J (101kg) but didn’t complete the clean. Completed C&J @95kg before these attempts.

Hit a snatch PR (66kg) which felt really good so got cocky and missed two attempts @70kg. I have a previous shoulder injury and you can see on the second attempt I felt a pull in my left shoulder when catching the bar.
