Drawing Competition - Page from a Book

[Evil Yoshi Toes]

Does it have to be a whole page or can it be a paragraph? Because a page is a lot to summarize in one drawing.

It depends on what you're doing. If you're doing a picture book similar to a children's book, there's often little text on each page. It could be that you're doing an illustration for a book with heavier text, but in both cases you should pick the most interesting and integral moment of the text and illustrate it for the best result. Like how in books with lots of text that contain illustrations don't illustrate every single thing that happens in the book, they only illustrate the moments worth seeing or moments which could use visual aid.
If you are going the route of illustrating from a text heavy story, you only have to include the snippet that you are illustrating, and I suppose you don't need to have that on the drawing itself since many books like that will have the text on one page and an illustration on the next. I'll update the rules on that.
I hope this cleared things up. Basically as long as it can be part of a book of some sort, it'll be acceptable
