Here we are; the finished version of the Retrofuturistic Gun my friend is getting for the holidays. I dare say he's getting damn near my best work ever. I call it the Gatekeeper.
When asked what style he wanted, my friend said "Steampunk with some post-apocalyptic thrown in". I interpreted that as a steampunk feel in a post-apocolypse weapon... kinda like Bioshock with a more art-deco paint job. Effectively, this gun would have been created out of the remaining parts from someone's shed after an 1847 armegeddon with an epicenter in Britain. Because of this, much of the aesthetically pleasing elements- though not all- were traded in favor of exposed tubes, rough knobs, and an overall less steamlined design.
I think it turned out pretty well, m'self. Hope you all agree and I hope you all had a fantastic holiday! And a happy new year!
