This is a Yorkie (although she somewhat resembles a long-haired guinea pig!). Well, the challenge didn't state that the portrait had to be human ...

If you're going to enter a slightly out-of-the-box entry, it better be really unique to score well. Something taken outdoors, with a nice background, probably a closeup, would have worked better. Good luck in the future!
I'm not a huge fan of pet shots, but this looks great! Not sure what it is, maybe the focus on the back of the dog, maybe the dark surrounding with good use of lighting. Nice shot!
