Lucien Freud (distant relative of the psychiatrist) captured the essence of the Queen very well, but the result is not necessarily nice to look at. He used his familiar impasto, technique, with thick application of paint and a harsh treatment of light. Most his work is like this, roughly rendered, but accurate.
It's just that there was nothing whatsoever about the person of Elizabeth R that was troweled on, rough or impressionistic. She projected both feminine and masculine energy as a delicately beautiful woman with a highly unique persona full of gravity, humor, strength, impeccable style, and spirituality at the same time. Light came from within her, not harshly glaring on her surface. She truly deserved the term “majesty.”
To depict her was an opportunity of a lifetime for him to grow beyond his long-established habits—a challenge for an older person to which he failed to rise, instead remaining self-satisfied in his hidebound ego. The result was not accurate; did not convey her essence at all.
Hardly a distant relation - Lucian was Sigmund’s grandson.
(another equally improbable grandson was Clement Freud - long-time regular on British TV quiz shows, TV cook and Liberal Democrat MP.)
