Hoskins taught throughout his life and maintained a genuine interest in the efforts of young artists. He was a founding member of the Wilmington Society of the Fine Arts and frequently exhibited his works there. Hoskins was a co-founder, with Frank Schoonover, of the Wilmington Sketch Club and, in 1928, a founding member of the Wilmington Academy of Art where he taught illustration, life drawing, costume sketch, composition, and antique classes. As magazine illustration began to wane in the late 1930’s Hoskins began painting portraits and historical subjects.
Hoskins was a versatile and prolific illustrator. He was an excellent draftsman and vibrant colorist. His subject matter ranged from portrayals of dramatic, emotional interludes to thrilling cowboy scenes and powerful historical depictions as well as formal portraits.
Hoskins wrote in 1950:
I have always tried to be as truthful in the telling of a story and in the painting or delineation of the subject as my capabilities would allow to leave behind canvases that may eventually become of value in their subject matter and a document of the period in which I have lived in the United States of America.
Hoskins died January 14, 1962, at the age of seventy-four.
