Ae Ri Cosplay went big with their Final Fantasy IX build. They made a giant, skull-covered Lich costume. It features a few points of articulation and eyes illuminated red by LEDs, as well as sculpted armor, fabric, and ribs elements. For example, those ribs were made from 15mm thick EVA foam they cut into strips and then finished by using a belt sander to remove the edges. Ae Ri used Worbla for the skulls; they explained:

All the skulls were made out of Worbla’s Finest Art, two layers of WFA and no EVA foam were used in these skulls. We used the WFA scraps from our previous projects. With Worbla, you can still reuse your scraps so it’s almost zero waste with this material!

Ae Ri used a Dremel Versatip (actually two Versatips, because the first one kinda died already)
to add the details on the skulls, the skulls are designed differently from each other, even the teeth has details and texture.

Before painting, I sprayed two coats of plastic primer, then two coats of primer grey, sanded just a bit, because we wanted to retain some of the rough texture. Then Ae Ri did her magic with her Iwata airbrushes.
