Concrit, please!

I'll totally see if I can find a reference (and if not, photograph myself stood in front of the mirror or something).

References are good for almost everything, especially in a situation where you need to make sure the anatomy is correct. Even in situations where you don't need the photo or reference for the exact thing, but are rather using it as an inspiration, the reference will contain details that make the inspired product more identifiable. Like if you're drawing a bow and arrow, it doesn't need to look exactly like a standard bow an arrow from several hundred years ago, but the basic shape and structure of the inspired result should still be the same or similar.

Basically, listen to Metaru/Gorsal.
