Sam,
Your grip is 100% better. Your stance looks about right and you are doing a reasonable job of pushing your knees out. Your bar position looks about right, but you are still trying to do a high bar squat. You are still trying to stay too upright (focus on sitting back much more and bend over more), and you need to adjust your head position such that you are looking at the floor (line of sight) about 4' to 5' in front of you. Your knees look like they are coming too forward over your toes, but this should get much better with a greater back angle (more bent over). Think about driving your hips up from the bottom, not your chest.
