For this character design, I chose a sci-fi brief. I gathered moodboards and references for the design of the gun and helmet in particular. Then, I sketched dozens of little thumbnails on paper to communicate shape language, aesthetics and functionality.
In the final character concept sheet, I included side view breakdowns of the helmet and gun, so as to help 3D modellers or other artists in the pipeline to better visualize the structure and form of the props.
