This is my favorite out of all the ones you did. I think it's because the shading/coloring looks really clean and neat.
Just for my own curiosity, how much time did you have to do these? I know if someone asked me to volunteer to do this project, I would have said YEAH RIGHT. This is why I hide from newspaper. Would it be out-of-place if I made some vague reference here about people being overly critical? I think you did a great job overall.
Oh, and I hope some rabid Harry Potter fans find these pictures and make you FAMOUS.
Then I can say I know you and be cool by association.
