It really does observe the game with lights and shadows, @velimir! In this case it highlights the center of the work, which in this case are the mirrors, especially that central! I like that the frontal reality is reflected in it. What gives the impression of a reality within another reality. That reminds me of a work by Jan Van Eyck. As for the masters, I see several present, by the formation of shadows could be Rembrandt or Vermeer. Right now the memory does not help me much! Greetings
