Charcoal practice

I was just practicing using charcoal in drawing using a reference from a book.

Elephant

Just a picture of a random elephant, done in charcoal.
Probably my first attempt to draw a realistic animal XD

More Mata Knight

Ah, I need to update more x.x
So here's more Meta knight I did last year, and I finally responded to comments.
Anyway,this was my second drawing I did in charcoal.
