[1] Okun's art is characterised for its reference to classical baroque traditions, which he identifies as tragic comedy in the tragicomic absurd perspective.

"The superb painterly qualities of the paintings link Okun to the European post-Renaissance tradition.

We can think of Giulio Romano’s Hall of the Giants in the Palazzo del Te, Mantua, from the 16th century, or some of the figures in the San Antonio della Florida in Madrid by Goya (1799), both wall paintings full of fantasy and severity.

From 1986 till 2023, Okun taught drawing at the Bezalel Academy of Art in Jerusalem as a senior lecturer.

By the late 1980s, Okun collaborated with Igor Guberman to broadcast "Eight and a Half" on Israel Radio.

During the 1980s, he received the Ofer Feniger Award and scholarships from Gestetners and the International Centre for Arts Cité in Paris.
