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 first question: What is your oldest OC?

My oldest OC (that I still use) is Sparrow. He's been around since about 2010 and he has had many design updates and changes over the years. For a while I was actually very unsatisfied with him. Since he is meant to be the protagonist of an RPG, for a long time I struggled to come up with a personality for him other than being a "blank slate," or something similar to a silent protagonist. He has evolved from a stick-figure thing to an actual human over time, but his(her) most recent change is certainly the most drastic, as I have now completely re-hauled his(her) design and personality. But yet this new Sparrow still has the same name, and very similar powers!
