Nice pic! Quite realistic, but only one thing i don't believe - this is the place where the ceiling connect with the chandeliers. Looks like they are flying)
If they were floating, you could easily see that in the mirror. (the distance from the lamp base to the mirror would be "different" in reality and in reflection, while here you can see that the distance is the same, which means that they are glued to the ceiling).
Looks like the contact shadows are missing, but it could be due to lighting, or could be due to some sort of denoising.
