The subjects of Hassan's paintings reflect a deep concern of social and patriotic issues on a specific level as well as philosophically abstract ones. Emotions which could have been reflected through famous events, were rather drawn in ways which could be by any nation or any place in many of his works. He stripped the players and the place of any specific nation and still could convey the emotions of the situation. Other works have been still more abstract in subject and even theatrical in nature by showing very simple experiential situations which reflects appropriately the more intellectual riddles of this world.
