Below are some images done by a guy named Josh Cochran. From concentrating on 'people' for my own drawings for this project, i found these really interesting and think they look awesome. Mainly the subtle blacks and greys, but i love how this really exaggerates the ONE bright colour. I try to, but i would like to do this more in my work. As he does short animations as well, i guess this is someone who works in a similar style to me.
