These Model Sheets look a little rough, but they have all of the details on them, so they are not Construction Sheets.
The Character Model Sheet is a complete version of the character from at least five different angles. These sheets provide the fleshed out design of these characters.
Brittany was invited to help design characters on 'Over the Moon', by Glen Keane. He liked her simplified style.

This provides a good opportunity to see the sort of character design work that is done for animation productions. Therefore relevant to Project 2 for ANI170.
You could do some of these for your character, as a stretch goal to take you beyond the minimum required work for the Project.

These sheets will show a lot of the characters in a production lined up to show how tall they are in comparicson with each other, so the animation artists can get it right when they do the artwork.
An Expression Sheet is used to demonstrate your character's personality through their facial movements.
(E.g. If your character has a grumpy personality, your expression sheet will be full of unhappy faces)
An Action Pose Sheet is used to show how your character will go about certain movements according to their personality and body type.
(E.g. A gymnast character will be far more flexible than a couch potato character)
