Being in the midst of social happenings, he returned to Bosnia immediately after the end of the war where he was engaged in creation of first Yugoslavia, with all his achieved political and penal reputation, belligerence and revolutionary mood.

In 1919, Stojanović went to Paris to pursue the best studies of art, which not only ensured the necessary education but also close contacts with numerous life's challenges and a creative stimulation coming from one of the biggest European metropolises.

The most vivid depiction of Stojanović and the whole atmosphere dominated in artistic circles and bohemian societies of Paris at the end of the second and beginning of the third decade of the last century was made by L. Trifunović: "Such a handsome and gallant man, with a shirt-blouse and black officer's frock coat, wearing a Borsalino hat with a wide rim, has entered early the circles of the Montparnasse Bohemians who lived around Rotonda and Cupola cafés, where people were drinking not too much and spending little money, talking, reciting, napping, passing time.

Another critic of Stojanović's artistic opus described the change that took place after his studies and return to the homeland: "After moving to Belgrade, Sreten's biography lost a sense of a happy story.

He seriously and professionally starts creating, establishing his first sculpture studio, exhibits his works at soloist and group exhibitions, very actively participates in the art life, writes artistic criticism, publishes two books, appears in public often and discusses professional or social problems at those times, gives popular lectures about art, grounds a family, travels..." During the Second World War he lived in Belgrade with his family and when the war was over he found out that his brother, Dr. Mladen Stojanović, died.
