After receiving feedback from Mark and the Tri Tag team, we settled on two designs made from a mix of a few of the initial sketches. I then refined the characters and illustrated them in their final look.
After the creation of Timmy & Tammy, I was provided with a script for each of the Tri Tag videos which I then adapted into storyboards, outlining the action and transitions, trying to add humour where possible. This example is for the rules video.
Here is an illustrated example of one of the backgrounds I produced for the Tri Tag animation.
