Scary Potter, a series of alternative cover art by Dylan Pierpont
(discuss.tchncs.de)
Community dedicated to the world of Harry Potter.
Mostly focused on books and fan creations, movie content is accepted but should not overwhelm the community.
I remember seeing it a few years ago, I'm pretty sure this is traditional art. I put the link to the artist website in the body of the post, you can have a look at their other work.
