I've had a few attempts at creating my self-portrait avatar, based on a photo of myself. I did a couple of sketches and I started by drawing on top of the picture I wanted to animate, and then refining it using Illustrator.
It's interesting to see the evolution of my appearance over time. From being bald to sporting dreadlocks now, it's like my hair has gone through its own design iterations. I guess you could say I've embraced a more "dynamic" hairstyle approach!
