Some advices, although they're just minor things, looking very good! Try using something like volume fog or depth map to make the lights trough the windows as realistic as possible, look at https://www.thegnomonworkshop.com/tut...s_shadow.html, and try to give every object a shadow with that, it would be in..... un.... arg..... not realistic if they wouldn't in such a bright sunlight. Perhaps the walls could use some noise texturing, to make them look less perfect, and the table's cloth ( don't know how you made it? ) could be just a little more smooth . but a very good job!
