I was checking the ferrin tag to see if anything new was around and I noticed that as of four days ago nearly the entirety of lumikin's character tag has had ferrin applied to it.
It seems like a bit of a strange situation, the character was originally designed as a Ferrin but is, with the exception of a few very early pieces, redesigned toward more generic features, which appears related to actions taken by the original designer and species rightsholder.
I personally don't consider Lumikin's current design to be consistent with the Ferrin species and the character owner themselves doesn't identify them as Ferrin anywhere I can find, but in a lot of cases the only noticeable difference is the fluffier tail, and I want to get some second opinions on what the lines should be for created-species tags before I start flipping back the ones that don't fit.
