I would like someone help me with my sentence please, regards

Do you mean this?
Art should be signed by the artist.

I mean that
when you look at the picture or drawings or sculptor, by style, by color, by grasping of chisel you should say this is Monet, or rembrant or Van Gohg, or da Vinci or Dali etc. If your writing does carry this meaning yes it is my dear teacher.

Art should carry an immediately noticeable feature which must then create an awareness of the producer herself/him

Some artists do have a distinctive style. However, students and copiers are so good at imitating and reproducing a famous artist's style, that even experts in the most prestigious museums and auction houses can be fooled.

How can I explain this then?

Some artists have a distinctive and personal style that is like a signature, easily recognized by people who appreciate them.
