Sls pe3 squat

Hi Guys

This is my form check for sls pe3 .....

Can you please critique my form ?

also I'm aware I have the problem of lumbar flexion at the bottom of the squat 

I'm currently doing all 3 stretch series and was wondering if certainly the front and middle split series  will help with this lumbar flexion issue over time . 

Many thanks

I like these reps,the only way you have (at your level) to improve the little lumbar flexion it is to increase the amount of lean of the knees.
