You should DRAW a Snape/McGonnagal ...thing! :-P That would be cute! EMO!SNAPE/McGONNAGAL! :-D Or you can also draw the Dark Lord peddling ties.

Keep 'em coming (well, take your time, because Rita is blowing outside my bedroom window as I type and it's only a matter of time before I lose power and won't know when I'll see them :-\)
