From my personal practice, here's an exploration session with a focus of playing with open and close.

Explorations like this are a thoughtful time for me! I often have strange looks on my face, or I stare into the mirror rather intensely. My brain is very active, as I'm silently talking to myself (keeping the focus in mind, noting what works and what doesn't quite come across - which is why I'm watching myself) and responding to what I see and notice.
