What I did first was read the brief first and follow it.
because it is very important to understand the brief given.

then I tried to make a simple layout complete with text and writing that should be on the book cover.
Next, I looked for an image that matched the theme of this book cover.

For the finishing process, I rely more on input from the contest owner.
and I tried to make several designs that were close.

the key is layout composition, balance, and readability.
