Some weeks ago I was commissioned by Runner's World Magazine to create the cover illustration for their Fall Shoe Guide. The only three rules to create the image:
1) Include a Runner Shoe (not brand specific but definitely recognizable as a running shoe).
2) A descent-sized open area to accommodate the title and info.
3) Reference the issue's season (Fall). So after presenting a few sketch-ideas this is the final result, I'm very pleased with how came out printed!
