It took forever to finish...
Here is the not-so-evil Sandra based on a photo she emailed me. I had to pull out a colored pencil to convey the color of her cheeks and lips. The original photo does not have the same serious mood that this sketch does. At first this bugged me... now I think I like how my pencil did more than mimic the picture. It seemed to add its own view, its mood.
Sandra, thanks for letting me "sketch you up!"
