Hitler tried unsuccessfully to be admitted to the Academy of Vienna. His paintings and watercolors, which you can find on Google, were worth perhaps to be used to do some postcards for tourists or folders for local touristic propaganda. He resented his rejection which he attributed to the Jewish members of the Academy. He continued to try a living in Vienna selling his watercolors until the war.
But he never made friends in his life, had one mistress Eva Braun who was always treated by him like a slave. Had many woman admirers, some of whom talented, like Leni Riefensthal, who died 2003. Hitler plagiarized people but never had any warm relationship with anybody, male of female.
