Tilt their head all weird when drawing? :O
I never noticed until my man pointed out the bizarre angles my head was taking when I drew stuff. I think it's just my way of accessing stuff and calculating, but it sure is a weird mannerism. I never do it during any other activity. Just drawing. And usually while drawing on an upright surface or painting digitally on my monitor. As far as I know, I've done it my whole life.
