Writers: If you're writing, then I'd suggest either watching the video and using it as a prompt, or (if you don't want to be influenced) close your eyes and listen to the song (or mute it and just watch the video). Once it is over, set your timer, and free write for five minutes. You could even add to a previous story or prompt if you think it would relate.
Art Journalers: You can sketch a scene from or inspired by the video, or take one image or series of images and use them in your art journaling page. Or do something related or completely unrelated but inspired by the sketch.
Don't forget - if you want to share what you've come up with, you can do it here in the comments or on social media with the hashtag #AprilCreativity.
