I found an amazing film with amazing music that was unfortunately unlisted from every major music service. I found out that the music was actually composed specifically for the film, but that did not stop me. I wanted the music score, so I found it on YouTube and downloaded it to my phone. The only thing that was missing was the cover art.
Subsequently, I found an image from the film on the Internet, and spent about 3 hours working on it to make the cover art. In the end, I just added extra sky to the cover. It looked way better without words, so I left it that way.
