I am starting a blog with my views on different aspects of running and running shoes. I already purchased an image from istock (attached) that I have used on another site. I just need the image redone with the head of the character to look more like me (I have less hair than the one attached!). Perhaps the shoes changed slightly to look more like a pair of running shoes (they currently look like football boots). Also perhaps the colors of the shorts and top changed too - I tend to wear black shorts and a lighter colored top.
I want to use it as a "logo" on the new site, but also an avatar at a number of social media sites,
