I was tired of the picture of books I had for the profile picture and I didn’t want to use my face, I didn’t want to confuse people. I found this really great site that was free and easy to use, avachara.com
Isn’t she cute! The head-shot is the perfect size for profile dimension with no cropping needed. I recommend giving the site a try, the avatars are endless with so many design features to choose from with a simple click of the mouse.
