Originally this was supposed to be just a simple test of applying gradient maps over black and gray drawing in order to color it like it's usually done in regular digital art. Colors and method is inspired by talented PeteMohrbacher . After initial sketch I thought there's more room for progress so I've decided to finish it. Maybe I could have polished some parts a bit more but I tried to render metal without references and multiple light source complicated things a bit. Overall it was very interesting drawing process and I plan to experiment with this process more in the future.
