PMS is a bitch...

That picture is really, really good. Your drawingstyle is unique and the lack of color only intensify the impact of your drawing. And that's the greatest strength of it:
You show in an impressive way the great difference in power and strength of the both characters, she shouting at him while her really big, hard packing hand chokes him, on the other side the librarian, helplessly grabbing her arm, struggling for breath and intimitaded by her anger. She really erupts her great annoyance over his whole body, staring with wide opened eyes at him, almost burning, the pose energetically and full of great emotion.
I like your drawingstyle, it's a little bit dirty and rough but that is the special flavour which gives your pictures lots of life and motion.
At all a extremely good artwork.
