You're welcome, I just went through my Miku folder and picked some where she is more or less floating.
Yes, what Crypton lists under her character art here is basically all there is for official canon (+ official artwork I guess, but that has no real coherency either, except for her base design). There is no one main official Story or anything, that way artists can portray her as a completely different character in every song/artwork/etc. Whatever fits their work best.
