Character applications are required to have a visual reference with, at minimum, a full-body image. (I want to be able to draw your character!!!) Art must be something you have the right to use! When in doubt, ask permission. As well, if you use art made by someone else, you must include credit- links are strongly preferred over names alone. Usage of dollmakers or free-to-use lineart are very welcome, as are simple or quick drawings! References don't need to be fancy, they just need to show how your character looks at a glance. Characters do no have to have strictly realistic designs, though should remain reasonable. As a rule of thumb, you should be able to easily imagine what a realistic version of your character would look like based on their image. Accessories such as plants or festhers stuck in the fur can be used freely, though anything human-made or that would require assistance to put on should have a backstory explaination.
