@ Halogene: Glad you like
The tail would indeed need new animations, though I don't think fitting it inside the hitbox is that important for now (no one would likely notice if it goes through a wall and such). I mean it might be best to fit it, but only if different hitbox sizes for different player models are allowed. And this would also mean that we'd need an L shaped hitbox, as the back of the creature would then collide in the air because the tail's collisions go all the way to the top as well.
But yes, it's not meant to be a fox model. I DO have a foxy I made in Nexuiz long ago though ^_^ But it's low-poly and I never got around to porting it in Xonotic. Perhaps I'll make another eventually. Not for official inclusion though... as an anthro raptor would work, but an anthro fox would likely be silly for a game like Xonotic by default
