The Anthem of the Kurzgesagt Bird with a Broken Wing

I really liked the new Kurzgesagt video about time, and thought it related well to Owl City's song Bird with a Broken Wing. There's also only a few fan made videos for Bird with a Broken Wing.
I know it's not perfect. I have a degree in English, not Multimedia, and haven't made a music video in about a decade. So, this was partially an exercise in re-learning basic video editing techniques using a new program. I used Shotcut for this video. Any constructive criticism is appreciated.
I used clips from these four Kurzgesagt videos:
• Did The Future Already... Did The Future Already Happen? - The Paradox of Time
• How to Win an Interste... How to Win an Interstellar War
• What Happens If We Thr... What Happens If We Throw an Elephant From a Skyscraper? Life & Size 1
• What if We Nuke the Moon? What if We Nuke the Moon?
