Haha, these are amazing!

Hagrid is so big!
Ron is adorable!
Hermione is so sassy.
Dobby looks possessed...
I love how McGonagall has her hands on her hips.
Madame Hooch looks amazing!
Marcus Flint looks EVIL.
Ginny, Molly, and Flitwick look very much like their actors/actresses, but Flitwick looks very scary!
Harry with the cloak is super fantastic!
