daydream brainstorm

I want to film someone (probably a friend) driving in the car from the backseat perspective. I will incorporate lots of scenery in Boulder in the video. The car will then stop at a stoplight. I will use footage from a red light where they are the front car and are sitting while waiting for the light to turn green. Then, the project will transition into a daydream. In this daydream, I plan to use all animation with lots of groovy designs and movement. I want the animation to look very bright and colorful. I want the character in the daydream to be picking flowers. The animation will then transition to an underwater scene where the character is swimming with fish and turtles.The daydream will abruptly end when a car starts honking at the driver (my friend). My friend drives past the light but turns red right after she drives into the intersection.
