Looks good mate overall.
Don't think about it, the double knee bend happens because of the 1st and 2nd pulls
1st pull, sweeps the bar in towards your hips/ hip crease
2nd pull, hips extend and your knees start to drive
THIS causes the double knee bend.
Looks good overall mate, just need to
-keeps hips down at the start a tad more
-keep arms straight for longer, they bend too early, use your lats to pull the bar in WITH STRAIGHT ARMS
-more forceful drive up with your hips
Keep it up!
