Can I use AI-generated images for this book cover?

Seeing some designs using the character references, so I added a few more character images to the brief for use as references.

I've changed the back cover text to read as follows:

The battle to reclaim the Sol System reaches its epic conclusion.

The surviving forces of the Terran Alliance have rallied at Proxima, standing with newfound alien allies in a fragile coalition. The battle lines are drawn, and final preparations are underway for a decisive assault to break the grip of the Conlok occupation and free mankind.

Across light-years, Mike Ashburn and Kara Vaelo remain separated by war and uncertain fate—bound by love and the hope of reunion. Meanwhile, Kusaka Shiguro races to refine new technologies that could propel a liberated Terra to the forefront of a new interstellar alliance.

On Mars, the Resistance led by the Crandall Foundation strikes back against Conlok occupiers and their Omnisynth enforcers. A band of youths comes of age amid deprivation and sacrifice, hardened in the crucible of war.

From the sands of Mars to the farthest reaches of known space, heroes rise and fall in a saga of interstellar conflict, first contact, and cosmic discovery. Humanity faces its greatest challenge—to face extinction, or rise and

Inherit the Stars

The brief has been updated as well to reflect the new back cover text.

pls check my design.thanx

If they are separate, will the size for the entire design be 12" x 9"? And which font should I use for the paragraphs?

Hi, I hope you're doing well. I think I messed up; I accidentally deleted my design, and I think it was in second place... What do I do? It won't let me undo the deletion. Thanks.

Yours was not either of the two winners this time, so you don't need to do anything. Thanks for submitting!
