Good work Brute.
For the back squats, I'd go with what BTB has mentioned. Really push those knees out to the side. Also put a little less effort into sitting back. Instead, let your knees move forward a bit more. For the raw lifter, just a little pop of the hips before going down is often better than sitting way back. A closer stance may also help.
Sitting back way to much with little forward knee movement is keeping the bar behind your heels as a result your turning the squat into a GM and your lower back begins to round.
For the front squats, you are also putting way to much emphasis on sitting back. Let the knees come forward, a lot more. This will allow your back to stay more upright and the bar to stay over your heels/mid-foot. What your doing now, the back angle resembles that of your back squat. Not an issue now, but as the weight gets heavier you'll lean forward to much and lose the bar. If you have no knee issues, instead of initiating the lift with you hips, start the lift by pushing the knees over the feet and let everything else move down naturally. If there is some knee pain or initiating the the lift with the knees causes discomfort, do as I suggested with the back squat... just a pop of the hips and let the knees move forward from there.
If your having issues getting the knees forward, look into some olympic weightlifting shoes or work on ankle flexibility.
Keep up the good work!
