This is Bloodmask, a character from my NaNoWriMo story. He's a creature known as a Wirrsa - a canine/feline hybrid. In this case, he is a lion/jackal mix.
Bloodmask is one of two male Alpha's who run the Goldgrass Pack, his partner being the male Sunspot. Bloodmask is Sunspot's opposite in most every way and is generally known fro being aggressive and very territorial.
