Ravenclaw Quidditch (9/7, Painter Classic) 
I really enjoy my new tablet - what used to take hours now only takes half an hour!  Here are Roger and Cho coming off the field. 
Irma Pince (9/8, oekaki w/mouse) 
A back-to-school inspired dealie.  I was mostly just satisfied I could scrawl out some words with the mouse...
Penelope Clearwater (9/11Painter ClassicDrawn out of nervous energy while checking on family and friends. But hey, it's Penelope - what happened to her?
Terry Boot (9/11, Painter Classic) 
There are very few males in Ravenclaw mentioned in the book. This is the only Ravenclaw guy Harry's age we've heard of.
Draco Malfoy (11/16Painter Classic)
I don't like Draco, but was inspired to draw by Quidditch uniforms and Draco's evil Pat Riley hair from the movies.
Poppy Pomfrey (12/3, oekaki w/mouse) 
An attempt at perspective, but I've also gotten rusty with using a mouse. That's Pepper-up potion she's trying to force on you. 
Viktor Krum (12/11Painter Classic)
A watercolor piece, maybe from Goblet of Fire.  He's sitting in the Great Hall brooding on Herm-own-ninny and her friends... 
Argus Filch and Mrs. Norris (1/7, Painter Classic) A character that was surprisingly cool in the movie and had hilarious lines.  Filch is now on my cool list. Mrs. Norris, too. 
Fat Friar (1/13, oekaki w/mouse)
A drawing that received several comments. Wow!  He always seemed so cheerful for a ghost...
Ginny Weasley (1/13, scan/Painter Classic)
I liked the way the Chamber of Secrets drawing came out, so I scanned it in and used watercolors.
