The world around Vincent effected his artwork in many different ways. Some of the main ways the world effected his art are:
When he worked as a layman preacher in Belgium in the coal mines he produced coal sketches of the area an example is the picture below:
Another way was when he took painting lessons from Anton Mauve at the Hague. The main way his work changed was the way he played with light and the looseness of his brush strokes.
Afterwards infulenced by Jean-Francois Millet he changed again and this time decided to paint peasants and rural scenes
In 1885 Van Gogh attended the art academy in Antwerp and got in touch with Japaneese art. The bright colours, the use of the canvas space and the role lines played greatly impacted him.
Later during his stay in a clinic (1889) Van Gogh changed his painting style again this time from dots to stripes and pencil strokes to spiral curves.
