You're probably right about the tail length. I get a little flamboyant when drawing tails (witness Yerzle's tail in the early strips. It's REALLY big!), and I specifically wanted it to appear longer than Sashi's tail, which is probably drawn longer than it should be.
That, and my consistency,as far as character design goes, is pretty poor (Ottavio's tail is also pretty thin in today's strip, as well).
