Canines are my favorite subject. Always have been, likely always will be. However, there are other families I'm quite fond of - cheif among these is cervidae. Five months ago, I made a one-off, simplistic deer character for a single piece, 'Neon'; more recently, I revisited the character, and crafted from him a caribou named Aaron! He's the newest member of my menagerie, and will serve well in NSFW pieces. 
Aaron is a different challenge to my sona, Ferin's sona, or Dario; his anatomy is fundamental different in places, which presents new challenges when it comes to using him in my art. That's very much a good thing; I need to push myself if I want to improve. Aaron is one way to do that.
