Nice work! Really solid start.
The one thing I'd be inclined to do is to try and jump your feet out slightly on the power jerk. This way as the weight gets heavier it'll be easier to dip deeper as you catch the weight overhead but still keep the bar over your centre of gravity.
At the moment if you needed to dip any deeper your backside would have to go further behind you cos of your narrow stance causing your centre of gravity to shift backwards.
