When trying to intimidate someone, always have a light source shining behind you, it gives that menacing glare that says "Hah mate you're doomed" another thing you should do is be tall, the taller you are, the more intimidating also glare, glaring is good, if you have blue eyes that'll double the effect because 99.9% of all villans have blue eyes [not saying people with blue eyes are villans- I know some rlly neat people who have blue eyes] Make sure you have an angry frown too, and have your hands on your hips- there, that's how you glare intimidatingly
