The first few words I wasn’t able to understand due to them completely blending together without having to replay it a few times, so make sure to watch with that when you are doing a character voice. This happened throughout as you stayed in a whispery tone so make sure your words are still clear and recognizable. Those who don’t have the script would have difficulty understanding what’s going on. You can still do this sort of voice as Joker with more volume so it’s easier to hear.
