Some characters I use on tumblr for RPs.
From L to R
We have Khara, ex-housepet who is basically a shaman/story teller for the pack. (5'7, 237 lbs)
Suri/Zury, scout who trails prey animals for the pack. Usually solitary, or found with a partner during the rainy season since deer are abundant then. (5'1, 210 lbs)
Briar, full fledged hunter/warrior. Usually partnered with a Scout so they can take down prey more easily. (5'11-6'0, 270 lbs)

They have softish scales like snakes, and are relatively warm blooded. Their hair is some fiber that is similar to human strands, and very fine feathers. None of them are poisonous, but colorations vary.
