I made this weapon based on original concept from Darksiders II game.
The whole process of creating this artwork was based on several steps:
-Base parts create using blender
-Detailing and carving in Zbrush
-Retopology again in Blender
-Bake maps and painting in Substance Painter
-Some post-process made in Photoshop
