[Quiet Man Cometh]

For me, clutter is when one can no longer distinguish the anatomical form of the avatar. 'Busy' avatars are fine, I've seen lots, and I don't mind item mush as long as it looks complimentary overall, but when I can't the general shape of what I'm looking at, or if that's a third arm coming out the side with feathers growing off of it, then I call it clutter.
