Avatars from left to right:
~My doberman modeled on Slink Hourglass
~Custom skin for  ChristopherFoxman modeled on Belleza Jake (and no he didn't model this for me, I did myself which is why the shape is off and the hair is different XD)
~My fennec version of my fennec mod I sell on my store modeled on Slink Hourglass (mine has freckles lol)
~My bull terrier modeled on Belleza Freya
~My skin of Surrie modeled on Slink Hourglass
