Below are examples of his paintings up into the early 1930s. Most feature women and interiors. Not included here are his landscape paintings and illustrations made while serving as a war artist during the Great War. I haven't found examples dated from 1935 to his death, so I do not know if he ever adjusted his style to suit changing artistic fashions.
At this date, he seems to have decided to use retro subject matter along with retro style.
Judging by the woman's clothing, I think this was painted in the late 1920s or 1930, and not the date found on the Internet with the image.
