I'm writing this from the past - which is not nearly as cool as the future, but until someone invents a time machine, this will have to do.
This little ditty (can I call a digital sketch a 'ditty'?) was created from scratch (that is, not based on a paper-and-ink sketch) using Sketchbook Pro. I used the mirror function to create a perfectly symmetrical image. It's a pretty handy tool, I must say. And, thanks to my new drawing tablet, and the neat pen and brush settings in this program, this piece has a hand-drawn feel to it. It doesn't look like a digital sketch, which is kind of neat.
