"The new freedom of woman by using the Burka as a means of showing all while hiding the essential."I have a few problems with this "art", if you want to call it that.
I find the practice of forcing women to wear tent-like garments disturbing. But these photographs are also disturbing, because rather than counter-act the burka, they actually continue using the same cultural language.
The faces of the women are hidden, so they have no identity, but with their nude bodies showing, with heels and garters, they are pornographic objects. These photographs could be read by a Muslim as "see, this is why women have to wear burkas--they are whores underneath".
Freedom for women wearing burkas would not mean showing their shaved genitals. Freedom for women wearing burkas would mean showing their faces. Then, a burka clad woman would have a unique identity, which what the burka seems to deny them.
