Thank you, that's all I needed to track down the rest of the info.
Sculpted by Steve West
Resculpted many sections of the kit to improve undercutting.
The broken Zeiram pod on the base ties this piece together with my Iria diorama.
The Zeiram drone was sculpted in Epoxy putty. The creature in the movie was frankly goofy looking. I went for a more "realistic" take on him, but tried to follow the original design. I added spikes, claws, a spinal column (instead of the clearly visible zipper on the original suit), etc. The graffiti on the wall is Keita Amemiya's name.
This is the same kit as in my diorama, but since I went to the trouble of paining his torso I wanted to document the work before I put the cape section on. It was too gorgeous a sculpture not to paint!
Thanks, Dave ! Updates added.
This bust was originally produced by Scott Andrews Studio, and is closer to 1:3 scale. I customized the bust with a jacket to be "Christopher Johnson" from the movie.
