Personally, the innards of a Portal 2 turret has never really interested me, but Alex Gabbott? This guy is curious. Not only did he think about it, he drew an entire cross section of it. Painstakingly. And recorded himself doing the entire thing. This is pretty awesome.
I got 185gm hot-pressed watercolour paper, which I then cut to A3. Prior to painting, I constructed a solid animation lightbox for about $70AUD, which I then used to trace my rough layout onto the watercolour paper. I then inked it, then painted it in watercolour paint. Because it is inspired by a video game, I was able to use Valve’e 3D model viewer to make it as accurate as possible. The final step was to scan it in, clean it up, and add annotations and shadows. See how easy it is? Simple.
Amazing, amazing job Alex.
