An early idea for Usonia was to make the suburb extremely blocky and modular, like it was made from prefabricated components and assembled on-site. It looked kind of neat, but ended up making Usonia feel more cold and impersonal than Nephilopolis proper, which was the opposite of what I wanted. Also here are some muscle studies of Kim. Getting the "exposed" arm to flex and rotate convincingly with the more natural looking physique was key.
We'll also soon be finding out exactly how strong Exode/Mark V Kim is (hint: it is very strong).
