A composite shot of the sapient species of Known Space. This is of course purely imaginative; no one has ever gotten a Tripod, for example, to stand in the same space as a human. A human would probably not be allowed to show their presence to a Shojin, either. A Qiqiu, for that matter, couldn't; the atmosphere would kill either the human or the Qiqiu for them both to be in the same environment. The picture nonetheless gives a good general idea of the different species' relative sizes.
Notes about how I do these images are available.
