This really is a fantastic picture and a subtle take on behaviour and control.
If there is one small thing that confuses my eye it is the overlap between the right hand/arm of the servant pouring the wine (the hand under the tray) and the arm/hand of the servant at the back left. They seem to overlap and run into one another. It is very minor, but I had to work a little at first to separate them.
Good luck for the finish.
