So, did you know I have a custom species? I mean, if you've seen my scraps:

you know that they're like elongated feathered porcupines. However, there's a lot more about them and how they influence my artwork. I really wish I could show them off a lot more than just as sketches. They're crazy awesome things. They can shapeshift, imitate light, heck they can even induce transformation and cause really weird things on the world, themselves, and victims if they wish ;).
The other thing is the fact that my fursona isn't just a foxtaur, but is actually one of these aliluks, and there's a whole lot about him that most don't really know, aside from a handful of friends. :P The problem has been the whole trouble of trying to make an entire connected universe where all of my characters just mess around in. And that is REALLY hard to work with. I mean, aliluks practically affect a lot...
For the Silhouettes canon, they're the influence of velokins (another shapeshifting species) and help them with their daily lives.
Aliluks caused Marco's modularity, and Piezo's techno-entrapment.
And they have a lot more crazy things, especially with Toc who should be drawn more. (thankfully  accidentalfox has been doing that often. :3)

So, should I draw more Vixiluk? Or a species-ref?
