1) Never seen a shadow flicker like that by turning head, that is really odd. 2) That is really odd, not sure what could be causing that. A new problem. 3) The backpack clipping is kinda unavoidable unless you want to play around in NIFScope every time you change gear. :) The hair in helmet is a little new... wonder if it's that particular hairstyle. I remember a similar problem to that with some hair remeshes.
