Extreme close-up! Probably it pre-dates my divesting the Bard of his rubber schnozz (not a deliberate move on my part, I was merely reflecting the reality of the lower illustration of his unadorned visage.) Now this could be a complete panel on its own, or it could be part of a greater picture. I think it would be a great cut from a panel of eg. a planet, starship / Darth Vader context, then returning the reader to action planetside with another round object thematically echoing it. That's what we'd do if this was a film storyboard. (It doesn't have to be a planet; it could be a marble, a navel or a nipple.)
There are more of these, most more substantial than this.
