whores of mensa challenge

Recently I've been rather naughty with neglecting my avowed morning sketches, but I am still resolved to plug on with them. This one came on assignment from ellenlindner and the Whores of Mensa. And what a fabulous challenge it is, Iris Apfel must be one of the world's most intriguing fashion designers.

Oh, and this came up on the web, people doing bizarre things in Photoshop to a picture of my sister. How very odd, someone please explain.
