Finally done, Killy blasting away with his GBE [Gravitational Beam Emitter] from the Manga series/Animated Film BLAME! by Tsutomu Nihei. This was a ton of fun to make! The background is actuallyt an edited image from the manga which I thought would be a little more fitting than drawing my own.
A big thanks to https://www.deviantart.com/null-entity for his fantastic stock which helped me to no end with the pose, cheers dude!
Total of 20+ hours work at least. Please zoom for details!
