WHICH ILLUSTRATIONS TO SEND?
You don't have to send all the illustrations, send the ones you like the most. The maximum number of illustrations is 10. The minimum is 5.
For example, you can attach only such illustrations:
illustration of a Character, illustration of the details of his luggage, illustration of a magic item, illustration of a new location, illustration of a landscape.
To compose a fairy tale and convey the mood, there will be enough small illustrations that will tell the reader how the Character, place or his things look like.
