I'm also quite fond of her countrified version named "Fiddlesticks". Will we be seeing either (or both) of them again in Season 4? I'd have to say the odds are very good that she'll be providing some music (and a touch of class) in the background of at least one episode. Will she ever be given a voice, and should she? That seems far less certain.
I really like this picture of Octavia, too, especially with that sly, playful expression you gave her.
I have been waiting and hoping you would make an Octavia for your ever growing collection of portraits. And it was worth the wait! I enjoy your art very much, and you have created an excellent Octavia image.
In other words, you're gooooooooooood.
