How long did that first one take to render, Warp.. forty minutes, with
(probably) the default settings? Probably more like two or three. Gee,
seems like a hell of an optimization to me, especially given your
apparent attitude that image quality is barely an issue next to faster
output. How is it that you made such a grevious oversight?

And why didn't you bother to light it properly? Why did you even render
it at all? What are we supposed to glean from this image, other than the
fact that you're apparently using a nightlight to illuminate the scene?
