I'm calling this week "vector week" and making myself do any personal work in Adobe Illustrator. I think vector skills will be good for me in the long run and, hey, I might fall in love with it! This illustration is 100% vector art, created in Illustrator. It took what felt like a long time to do but I think speed in the program will definitely come with time. But I had fun!
I got a request in a comment to post a more detailed view of one of the faces. It's great idea! I'm posting all three. There's nothing too fancy here; just simple shapes on several layers!
