How many camera angles do you want to have for your artwork (Example, front and back shot)
The shape of the artwork determines what it can be used for. For example, some clients want their artwork to be used as a wallpaper for mobile (Portrait), PC/console (Landscape)
You get 2 versions of the same artwork. A variation is another version of your artwork in which things are slightly changed. Example, the characters can have clothes on/off or wear different outfit. We can discuss different possibilities

Describe your idea of the artwork as detailed as you like.
