I've drawn a cute little harpy, for your viewing pleasure. Please don't mind the tattered top; I had to keep the picture safe for work, as per the blogspot terms of service.
It's been suggested to me that I add some downy plumage to her chest, in the cleavage area, and the idea seems to have some legs. I think I will adopt that design change, but the current image and current physical description will stand as they are in the blog. When I start building the wiki and draw any more pictures of harpies, the change will be reflected then.
