I did an OC Meme over on Twitter last week, and I drew a few pics as a response to some of the questions.
The fourth question: What is your favorite OC Design?

I like the designs of all my OCs! If there is a design I like less, then I'll change the design until I like it. But one particular design that I've always really liked is Orion's. Many years ago he was just a stick figure, but I created a modern, cyborg design for him in 2015 and it has stuck ever since. Even if he gets minor changes every year or so, the basic concept behind his design remains the same. He is normally human, but his nervous system is connected to a very strong metallic exoskeleton. Whenever he tenses his body, the metal casing surrounds him. When fully cased in the metal body, he has very large arms and a long razor-sharp tongue, among other things. The only thing inconsistent about his design is how much of his internal body is robotic. I haven't decided on that part yet.
