I too struggle seeing this shot. While it's focused, it's also too dark. Personally, I would have backed the show out a little more to give a little more point of reference.
For in and out, above, about, below,
'Tis nothing but a Magic Shadow-show,
Play'd in a Box whose Candle is the Sun,
Round which we Phantom Figures come and go.
