RE: good form?
it also looks like you're bending your neck forward to look thru the peep. hard to tell from the angle, but that's what it looks like. your neck will sure feel a lot better in the long run if you don't do this, and you'll shoot better too. once you turn your head to face and aquire your spot, it shouldn't move when you draw. your peep should come into your view, not the other way around.
