I first drew the heads and did the lettering by hand using pen, brush, and ink. I then scanned them into the computer and played around with the colours as I arranged them in Photoshop. Whenever I do a project like this I am quickly humbled by how little I know about Photoshop. I can make something work, but I go about it in a rather gruesome way. I need to check out some books from the library.
Overall, though, this was a good experiment in combining both freehand and digital work.
