They'll be a self-published series through Lulu - so first an actual physical book and then - once I work it out - maybe an e-book. But I'd prefer a physical book, since they'd be art/information books, to give people an opportunity to own a book of the totem art, who can't afford an original.
In the meantime, I have over 76 Australian totem animals along with artwork represented on my website: www.wildspeak.com
Have you ever done any plant totem? hmm, an orchid would be wonderful! Why not Australian orchids, as Australia has some of the coolest orchids! If you need some inspiration take a look in my group gallery, it's linked in my signature btw. There are some wonderful species in there!
Anyway, I think you should do Endangered, Asian or Australian animals!
We do have some of the most wonderful orchids. I enjoy taking photos of them, though my favourite is the relatively common donkey orchid (Diuris magnifica). I haven't illustrated them as totems, mostly becuase of commercial reasons (i.e. plant illustrations rarely sell compared to animal illustrations), but maybe I could do a plant totem book down the track.
