I felt like scanning a practice round for no appearent reason. A friend and fellow internet troll told me a brilliant technique that I was too retarded to utilize before. "SCAN YOUR SHIT PRINT IT AND COLOR THAT CRAP" He uses caps because it's the only language they speak on those chatrooms.
This round consisted of shading using only a black pen.
From left to right:
Crosshatching: Never again.
I don't know what it's called when you do the lines all lined up with the light source, but it was a pretty good first shot for my first try with it.
The third one is the main reason that I wanted to post this. I think it looks frickin' righteous. Also I haven't posted anything in a while so meh.

Practice makes pancakes.
And I didn't have to butcher the original lineart or make a new one just to fiddle with a new shading technique!
You can't spell scrapped without crap.
