Indeed. I once saw an oil paiting of his in London's National Portrait Gallery (he modelled for a friend who's a painter). Brownisch hues, facetted shapes. That face is almost Cubist on its own. Have a look: walktofreeartlondon.blogspot.d…
Thanks for the link! I first saw these portraits. Peter has very interesting facial expressions and emotions are multifaceted. It's very inspiring, I want to catch all details.
