Interesting concept of Witch attire. Strays from the usual generic witch style and makes you see the traditional witch character in a different light while still being recognizable as a witch.

Also still keeps a few of the trade mark garments like the hat, boots and stockings.

The bow in the hat is also a nice touch. I am unsure as to what the things are sticking out of the bust but in colour they may make sense.
The flowing look also adds to the grandeur of this figure, also the scarf is a nice touch.

A bonus would be the colored version.
