Good day.
This is a video done with #Midjourney, #Krea.ai, and #Haiper.ai.
The basic prompt for Midjourney involves the use of the --sref 3226746490, which will give your images that greenish tone.
Krea.AI loses the illustrated feel when using its Video, but adds a lot of amazing movement; Haiper manages to keep the style, but add way less movement.
Cheers
