Alright, here we go!
This here is a canine-based species (of no particular species, really, just somewhat similar to a canine), and the tail is a bit reptilian. The little orbs on their tails are extremely fragile, and are the physical embodiment of their souls. That's about all I can give for now - PM me, post here, or any of that to request permission to make a copy (owner of comp only) or to receive additional information on the creatures themselves.
