Here, I'm allowing "degenerate" petals — those which self-intersect or twist. The final representation is a pretty good match, but I'm not happy with the appearance of many of the shapes. (The super-hero-mask eyes are particularly ugly.) On the other hand, a couple of the nice shapes (like the hair on the right side) wouldn't have been allowed by the radially-sorted petal algorithm.
Currently, right here. It's a work in progress. More soon.
