I don't have much Harry Potter pieces but I always seem to noodle on a piece when my wife and son have a marathon viewing.
I've always wondered about the backstory of Tom Riddle and how Dumbledore is partially responsible. I find it similar to the Obi Wan/Annikin relationship.
So here is Tom Riddle. Unfortunately the resolution is lower than normal as I did this one on our old first generation iPad as I wanted to draw a bit bigger than my iPhone allows.
