I found your previously unreleased image was part of the book Incredible LEGO Technic from links to kotaku and Amazon: http://kotaku.com/some-of-the-best-lego-uses-more-than-just-bricks-1651045658
Could you post a verification somewhere publicly so that more than just @logic can see please?
Is it okay to post a new photo of the tank with a date on paper next to it? I think the photo I made for Sariel's book is not released on internet before. I quess I'll do a proper introduction post with maybe some sort of selfie with my creations behind me or something :)
Sure go for it
