I'm excited to announce that the first piece of exclusive OpenGameArt.org art has been completed! You can find it here. My eventual goal is to commission various sets of armor, hair, faces, etc, (as well as a female base sprite with similar options) that will allow developers to build sprites to their specifications. For the time being, customizing this sprite will be up to you, the community. Please remember that, since this art is licened under the GPL and CC-BY-SA, you are required to redistribute the source of any modifications you make to it (in this case, any Gimp, Photoshop, or similar files that contain image layers), as well as crediting the original author.
