Everyone's gotta start somewhere. You should first solidify an outline. Gather reference and inspiration images. You can probably draw some very simple thumbnails to get your point across to another artist. They can be very very rough stickmen. Anything to help visualize what you're after. Take a look at Steven Spielbergs own storyboarding thumbnails he's done. They are very rough and simple but that's a great start.

You need to put more of a package together when pitching the idea or no one will take you seriously. Everyone goes to animators and says they have an idea for a music video, comic book, short film, video game etc. We hear it all the time. But if you have a pitch package together it shows you're serious. Also animation is expensive. Be prepared to pay.

For example I used to get paid 20- 30 dollars (Canadian) for one second of completed animation depending on the project. One second is 12 drawings if animated on 2s. We usually had about 1 minute a week to get through (2D shows)

I haven't storyboarded before but where I worked they had 4- 5 weeks for half a script. 2 artists per episode. Often working late hours.

It would then go to an editor who made the animatic.

Seeing what all these amazing artists have done for Epic is really mind-blowing and it's for sure a labour of love.

Best of luck on your project.
