i've done this project in 2019. when my friend "Jere Fundamental" the Finest Rap in my town release a single called "Killah Maquinah" the song's about criticizing politician who didn't care about their responsibility making good life for society in their country. Killah maquinah it's a representating words from killing machine. 

so the first thing i do is making a concept sketch. so the artwork has a message even in a one completed picture.

after that, with some talks and thoughts. we finally make little changes for the concept

and i straight to making the artwork. here the progress from the line art into finish.
