Here is the current state of the Pantocrator icon on the dome. The degree of intensity of the colors, the gold and the surrounding images will depend on the amount of light coming from around (through the windows) or from below (chandelier).
And in case you are wondering, yes, that is real gold leaf on the dome.
This shows a wider view of the dome. The scaffolding precludes seeing all of it at once - I had to lay my camera on its back to get this shot.
There are six cherubim up there, on the inside of the drum, and they have almost exactly the same expression on their faces. I couldn't tell the difference between them.
Here is a closer photo of Jesus, from a different angle.
and a closeup of his hand holding the Gospel book or Bible.
He awaits.
