oh gosh, it's artdump time xD
Harry with Hedwig. This one turned out great, in my opinion.

Sirius. He looks rather underfed, but he just escaped from Azkaban so it's understandable

All six DADA teachers! (I refuse to recognize Carrow as a legit teacher.) It reads Defense against the Dark Arts Teachers at the top, and left to right, Quirrell, Lockhart, Lupin, Moody, Umbridge, Snape.
3nodding I really like it a lot. I think I captured the character's personalities quite well.

Ron & Hermione with Crookshanks and Pigwidgeon. Very cute

Bellatrix, looking evilly triumphant. Again, you can't see the text, but she's saying, "Muahahaha! The Dark Lord will rise again!"

Lupin and Tonks.
3nodding Aren't they cute? I used a different hairstyle for Tonks this time, but I really like it. They're both wearing house scarves (Lupin = Gryffindor, Tonks = Hufflepuff). lol, they make a good couple in my opinion, even though no one else agrees.

Snape. 'Nuff said. <3

Young Dumbledore & Young Grindelwald examining the Deathly Hallows. You can't see the text real well, but Dumbledore's saying about the Invisibility Cloak, "With this, I could be invisible!" And Grindelwald's saying about the Elder Wand, "With this, I could conquer the world!" with appropriate evil-conqueror pose. xD

Dumbledore, looking oddly Gandalf-ish, standing with Fawkes. I know it looks like Fawkes is about to make a crash landing but he's just sitting on Dumbledore' shoulder and stretching his wings xD
