what if elven eyes do that creepy thing where they reflect light back at you?

Not to… hijack your post, but elven eyes should in fact, absolutely do this.

In nocturnal animals, who have a far superior night vision than humans, there is a layer in the eye called tapetum lucidum that reflects light back into the retina that both helps the eye take in more light, and causes that glow-like reflection. So elves, who have darkvision, should do this too. Actually, theoretically, any fantasy race that has superior night vision should do this to some degree. 

I love that you’ve drawn this, it’s a great concept.
