An older project I didn't finish a while back so I decided to finish it up in UE4. Textures are done butttt they are all in 1024!!!. So I have to work on that, but the bright side is I can experiment more with Substance Designer. Maybe integrate SubD in UE4 using the plugin. Lots of tiling to do and updates coming soon!
References I'm using.

I think you could also use a little more AO in the scene. There's quite a bit of darkness in the crevices in the reference that's absent in your version.
There's also a strange lack of shadowing throughout the scene. Maybe it's just me but it looks sort of weird where there's ceiling lights but no shadows (or maybe it's just the global illumination if you're using that).
However, if you aren't already using global illumination in UE4 it would probably be incredibly beneficial for this scene.
I think I actually liked the original ref with the overly warm tones, made the space feel a bit more inviting than what you have here. Maybe add a little more color to the lights? The sepia tone was helping a bit, but I think you could push it a bit more.
You are also not getting a feeling of contact between the pillars and the floors. You could grime up the bottom of the pillars a little bit to make them feel more seated. Look at your ref, for example...it makes a huge difference imo.
