Your eyes should make you look like a scared doe at all times.
You need to always be smiling or pursing your lips. When you purse your lips there should be a small opening in the middle. For example, pretend like you are kissing the head of a cock. Go ahead and practice a bit.
Tilt your head slightly to one side. This helps convey that you have no idea what is going on to anyone who looks at you.
Tits out, shoulders back.
