I participated in ArtFight during the month of July, an annual event that has apparently been going on, totally unknown to me, since 2007! I can't believe I had never heard of it before, so though this was my first year participating I anticipate that it will not be my last >;)
This character is Arsen "Sunny" Luna, who belongs to Elmsycat on Tumblr, drawn in response to this adorable chibi they made of Catriona.
