I've been told I look like I'm bored (although I'm not)...no facial expressions. I move around, but apparently my facial expressions hardly ever change.

I've also started paying a lot of attention to my technique. Just recently did I notice that most of the time I rest the tip of my pinky on my bridge pickup (with my picking hand of course)...Just something I do that probably most other players do that I never really paid attention to. I also will change from holding the pick with my pointy finger and thumb to my birdy finger and thumb. Don't know why I do that, just something else I noticed I do a few years ago.
