My style of artwork has always been quite detailed and rendered. Tee shirt creation is a great diversion for me forcing me to strip back my style into the most basic shapes and concentrate upon placement and design to put across a message.
In this case the temptation, which I have avoided, would be to add detail to the running figure to emphasize his musclelature. Instead I have drawn the silouhette and reproduced it several times in different shades give the feeling of dynamic movement.
This tshirt can be customised so that you can add to it any slogan that you feel would inspire the wearer.
