I'm definitely NOT a world record front squatter or anything, so grain of salt this advice.
1) I like to grip the bar less than you currently are, it encourages me to get the bar back more closer into my neck and more balanced by my shoulders. Plus, helps keep bodyweight back (which is key for me front squatting).
2) I like to have my elbows out wide at the top for a couple of reasons....a) helps me get a tight thoracic spine (important for controlling trunk posture)....b) cause at the bottom I like to drive up with an initiation from driving my elbows closer together (kindof where you are) which helps keep my tight and back (stops me tilting forward).
3) I try not to muck around so much with my feet getting set-up. You narrow up then go out again prior to squatting - waste of time and energy IMO.
Again, grain of salt my advice, there are much bigger front squatters on here than me to give you advice. Try and find a cool vid of H4M doing a 180kg front squat with arms out parallel - then listen to whatever he says
