This illustration was for Running Times magazine about the psyche of runners and how they are never satisfied with their achievements, always wanting more.
The editorial team wanted to incorporate the illusion of M C Escher's 'Infinite Staircase' to convey the runners mindset. It was then a question of the setting and how best to integrate the staircase with other elements.
I always start out with the intention of producing a simple graphic image (believe it or not) so positioning the staircase within a silhouetted head seemed a good way to go. Adding the runner on the stairs for the main focal point and then including a stopwatch face to emphasise the theme and that felt enough.
