Wow. This is old, but I like it. Fake mech detail entertains me. This was drawn to be a dim background image on my old website... the linework was dark green on a black backdrop. It was also smaller, so between all that you weren't able to read the text.
For those wondering, this skeleton is based on the CGI rendition of Mega's internals form the 10th anniversary book cover.
Also... ignore the use of Japanese names. I'm over that shit now.
