I think the process of writing good poetry is very similar to painting in non-conventional styles, in some ways there is more in common here than there is with prose-writing. The more radical the approach the more interesting. Here is a selection of self-portraits that stand out; artists that can do these, I think must have that poetry thing. Indeed I think dwelling on any of these for a while might well inspire a poem.
Schiele in typical Schiele fashion
Francesco Parmigianino's Self Portrait in a Convex Mirror; I love the hand.
Tintoretto seeing himself with rheumy eyes
Dali company-keeping with bacon: Soft Self-Portrait with Fried Bacon
Escher Self-Portrait 1919 Woodcut
Courbet (forgot his mobile)
Difficult to decide which Kahlo, but this has some of her trademarks
Francis Bacon looking pensive.
