It's like an extreme paintover, heh. Kind of a strange case since he changed the design so much. I think it's clear he didn't intend it as fanart, since people who work on fanart usually are quite eager to promote the thing they are making fanart of. In the end it comes across a bit suspect but it's morally ambiguous…
i just saw this artwork in 2dArtist Magazine(038 interview with Chen Lin. Fanart or what? http://wanbao.deviantart.com/art/Mechanical-soldier-66894917?offset=10#comments i don't see any credits for Taehoon Oh(model)James Chung & Karl Ostlund(design), is that fair?
