Hello. last days I was workin on project “Korus”. I don’t know what add or change for make it more realistic. Can someone give me a tip, please ? (And excuse my english, please.)

I don’t really know what I’m looking at but as a critique/suggestion, perhaps change the lights and more of it.

Could for example use the open windows, leave the main subject matter in the shadow and get bounced light on the other side, maybe something to this direction
