Do the chandeliers look too big for the room size? The room is ten blocks tall and with only a one block elevation of the throne, the chandelier is directly in line with its peak. Not sure how to fix that. Might try a different through maybe from dark oak or pale oak. Any ideas would be appreciated. I probably don't need chandeliers. Could use light sources under the carpets but they help make it look more grand.

I like it so far.
I'm just throwing out a bunch of ideas, they may or may not work out. Play with stuff until you find something you like.

The chandeliers are a nice addition.
The ceiling space to left and right is left empty, I think some banners on the beams, either brown or dark green would look nice. If not banners, some kind of feature that smaller than the lights.

I think overall the wood color is a bit flat.
Break it up a bit, maybe outline the carpet with a dark oak or different color wood for the ceiling planks and log beams.

Similar thing with the pillars, the arches are nice and I like the detailing around the tops and bottom, but put something in the center. maybe a banners or tourches. [edit, looking at this again on a bigger screen, I see the fence and laterern are right there]

Also the stone wall behind the arches may benifit from some variety, maybe inset the center column and a put stone wall there. For the ceiling, in the flat section between beams, slabs of same block can add depth in a few styles. Either a checkered pattern, or raise the center 2 rows up a 1/2 block so it looks like each section is vaulted.

(This part is defiantly my personal style)
Finally, think about how the architecture and throne interact. Right now it looks like the throne was just thrown in the middle of a hallway. A good throne room will look like the room was built around the throne.

If you take the suggestion to boarder the carpet with a dark wood, maybe that continues around the throne. Maybe the pillars become larger around the throne, or the arcs in the back curve to mimic the throne's outline. It should be an architect's finest work, not something they threw together on a Friday afternoon.
