Possibly what Ria looked more like when she was younger, but she's a powerful shapeshifter and doesn't like to appear too intimidating. And she likes the male attention. So, less muscle, more curves. Also, the scales are dragonscale, not metal, of course.
I'd wanted GreasyMojo to draw Ria for a while so I was pretty excited about this one. I really like her proportions! And I liked the golden-colored patch on her crotch fur so much I made it canon. This is one of her default refs now.
