Occasionally make movie posters for YouTube videos I download, primarily using low-tech means like cropping, layering, etc.
Mainly because I don't know how to do the more advanced stuff, but I find it kind of fun though to try to do similar levels of quality with lower-tech tools. Kind of like coding challenges but with Paint.NET. Lol. (BTW, that's not a link. Lol.)
Did you watch that short movie that someone here made a few months ago? It was about a doc who dresses up for Halloween. It was really good and making a poster for it would be cool.
