A ref of one of my more often used or depicted pups; Katrina.

I don't think I would need to say who did this ref either considering the previous two images.

In case you're wondering why she wears a mask, I tend to see it as she got badly burned at one point in her puppyhood and so wears the mask to cover it up. Rather than say being malevolent like THE Phantom of the Opera, Katrina keeps to herself and is shy, fragile, but sweet and gentle. And quite frankly, I tend to imagine her singing as being...heavenly.
