From the top, you're breaking at the hip, then later breaking at the knee. Hips and knees break at the same time. Hips go back and knees forward/out. Get your knees set in place about 1/3 to 1/2 way down, they just sit back and down.
You're also going way too deep, cut it off by a few inches and see how that looks. 1" below parallel is ideal.
Lastly, I can't really tell from this angle, but I think your knees might be collapsing in a bit on the ascent. Take a video from the rear or 45o to get a better look.
(Also, might be good to invest in some squat shoes.)
I actually worked on breaking form hips first then the knees. Didn't realize that its supposed to happen at the same time.
I'll work on breaking at the same time, and reduce my depth before posting again.
And yes, on heavy sets my knees tend to fall inwards when I go up. I'll continue to working on this as well.
