Are you a female? Just asking because those weights are on the low side. I think your leg day sucks. Maybe focus on either the deadlift or squat for a month and then switch it around.
For example I do this
1)Squat or deadlift 1-2 heavy ass set(s) of 4-6
2)opposite of whatever I did but more of an assitance exercise (stuff like RDL's, Stiff legs, Single leg work, leg press etc.)
3a)Isolation quad 4x8-10
3b)isolation ham 4x8-10
Its pretty simple but it seems to work.
For the front squats, I do the oly grip, but it always rolls into my neck and makes me feel like I am going to pass out.
