Because she has a tiny head.

I have lied in a couple puddles of blood in my day, and from experience I can tell you, it stains your pig tails red!

hmm...it looks like she is laying on a silk scarf, surrounded by jelly beans

...or rose petals.

So it's Morrigan cosplaying as Lei Fang?

That's quite the stretch, though nice artwork.
