Hopped into tokalub's stream yesterday with a silly little idea that they were happy to sketch up for me :3
Kayana is, depending on my mood, either based on the Worgen from World of Warcraft, or IS a Worgen. This leads to the issue of whether or not she should have a tail. Personally, I like tails so she gets drawn with one even though I know that's not strictly correct.
Here is one possible explanation (or excuse!): Someone has burst in on Kayana getting ready for a night out before she's put her tail on :3 Yeah, I thought it would be amusing to depict her as having to wear a fursuit-type tail for once :)
I would like to get this sketch upgraded to at least clean lines at a later date which the artist is willing to do.
