TO CLARIFY:
1. Jesus is on the throne because that's where he was installed since 1914. (according to WT doctrine)
2. The Orbs at either side, are angels known as "Thrones", which are typically shown as Orbs. They represent God's Love, judgement, steadfastment.
3. The large winged guy on the right, is Michael the Archangel. (or possibly 1 of the other 2 mentioned in the Bible) He's not Jesus, because he's not wearing a King's Crown. A lot of people forget about Michael, but there he is.
4. Jehovah isn't shown because how are you going to show Him? He's everywhere all at once and inconceivable, so they don't "show" Him. Although, He might be represented as the bright glowing behind/above Jesus.
5. I think they made the rank-n-file Sheeple actually stick out more in this illustration. How so? Well, those in Field Service (bottom right) are the largest photos in this whole illustration. The GB at the table are actually the smallest!
I frankly think this is a mountain out of a mole-hill with this illustration. There's a lot of things we can hammer the WT on, and this is frankly a big nothing-burger.
