Lord of the Rings
Seeing as Lord of the Rings is my favorite movie (yes, the whole trilogy counts as one single giant, epic film), it's fitting that my very first collage wallpapers back in the day were for Jackson's beautiful masterpiece.
Morning Star
Lucifer, the Morning Star, bringer of light. I've never been great at photo manipulations but I think this one turned out okay.
The Marauders
The Marauders and the adult characters in general, including their backstories, were the absolute highlight of the Harry Potter series for me, and I'm still incredibly bitter that they completely left that huge, highly important part of the story out of the film adaptations.
