RE: form
It's the wrong angle shot to tell, but it looks like you MIGHT be bending your neck down to look through the peep. Your neck and head should be stright up as the top of the "T".
However, rotating your string elbow down and bending your bow arm just slightly will also settle your anchor point a little lower which will require moving your peep up as well.
When you do have your peep moved up, make sure that when you draw that you are able to look through your peep without craning you neck in any way. You should be able to close your eyes, hold your head up tall and neck straight, draw your bow, anchor and when you open your eye you should be looking right through your peep!
