I've decided to post this picture as a lesson on how to use the brown eyes.
1. Keep your head low. It's best if it's resting (as seen in picture).
2. Look up just slightly to raise the eyebrows.
3. Putting 1 or both front paws right next to your face. They act as a frame for your look.
4. Keep your ears perked.
5. Stay focused on your subject.

Results? Melting your humans heart and likely getting away with anything!
