“I follow no system of brushwork at all; I hit the canvas with irregular strokes which I leave as they are, impastos, uncovered spots of canvas — corners here and there left inevitably unfinished — reworkings, roughnesses; well, I’m inclined to think that the result is sufficiently worrying and annoying not to please people with preconceived ideas about technique.”
Vincent van Gogh, letter to Emile Bernard c.12 April 1888
Or put another way: don’t stress about your brushwork so much, do what you enjoy.

Well he says that – but how come we can all recognise a Van Gogh by his brushwork?
And it’s distinctive from a Cézanne too… Maybe it’s the energy in the brushwork?
