I do not know what your question means: 'after Picasso' can mean that a work of art is copied or paraphrased from a Picasso work. Or maybe you mean 'What has happened in the art world after Picasso's death?' In that case the answer is that since Picasso died in 1973 nothing really revolutionary has happened. Pop Art was already under way, of course. We have had Minimalism, Land Art, various types of Installation. Definitely later than Picasso are video art and computer art.

Picasso did not make the scream. Every famous art piece is not made by Pablo Picasso. It was painted by Edvard Munch
Western art has gone through a revolution in the 20th century. Picasso's work is one of several strong forces behind this revolution.
