I don't think there are many figures that can be interpreted with such a wide range of motion without losing their original proportions.
The lower back bends firmly, and since you can take a forward-tilted position, you can stand comfortably on your knees.
It also has a large number of attached parts, so you can see that it took quite a bit of effort to realise it.
I would have liked it to have a fire effect accessory instead of having to use mine. Other than that, nice figure.
