This mech is heavily inspired by the same-named concept of Okubo Junji, this is from the book 'Industrial Divinities', sorry no reference available in the web.
It looks quite armored core like.
I am not happy with the outcome. Luckily the joints are just strong enough. First I thought on giving it a colouring, but as I am not really pleased with the whole shaping (The reference model is much more sleek, not so bold) I won't do any surface work with this one.
The gun barrel design is adapted from nnenn.
