Wow man, that’s solid work!
Only nitpicks I can think of:
The movement of the flame lighting from the torches on the walls feels slightly off to me -It feels like the lamp texture goes from lit to unlit, I think if it was a bit lower contrast to that even the darker sections were still somewhat lit it would sell it more. If you study scenes lit by flame it’s surprising how soft and uniform it is in many ways. Other than that detail the lighting is spot on.
Some more variation in leaf size on the vine might sell the scale of the scene a bit more: I love how well the large leaves read at a distance but if you got some smaller leaves in there as well I think it would make the space feel larger. That foliage also kinda begs for some subtle movement, you do a great job of selling the atmosphere around there with the particle effects so I think if those leaves swayed in the wind just a little it would really bring together that sense of open airiness pouring through the skylight above.
