Squat - you have a really narrow stance. Open it up a little bit. Make sure your feet stay planted on the ground - you are rocking towards the toes and the heels are rocking up a little bit (that could be those shoes). You need to learn better pelvic control (this may be partially because of your narrow stance) as you get a pretty large posterior pelvic tilt on the decent of the squat. Work on staying tight and pulling yourself into the bottom.
