How do I pencil art

I don't want to upload this to dA because... BECAUSE I DON'T.

So I'm dumping it here.

Main reason why I made it - I wanted to learn shading/blocking out faces (LIKE I AM GOING TO SUCCEED AT THAT HAHAHA /slashwrist) and because I like working with graphite pencils. :I

There's endless mistakes here. Also it's hard to tell where the crosshatching ends and where Raven's beard begins but that's least of my problems. Somebody could teach me how to make clothes look good. THE VEST LOOKS WONKY AAAAAAAA
But I already hairsprayed it... yep... 

Well ok this is it. Shitty art yep.
