Looking Good Eric, one suggestion I got from a good Coach, use one of those warmup\\training stretch bands to work on that follow through, it will help make it become faster and feel more natural.
I kept mine around the house, every now and then I would pick it up and do a Release and followthrough (20-30 times a day), it only took me a week and my follow through was much improved and saw a lot less stray arrows in my practice groups.
