Develope 20 designs for Denim Jacket

I am going to introduce designer denim jackets for both men and women. I need you to help me to generate some unique designs which will be applicable on the back side of the denim jacket. The AOP designs are also acceptable. I made my mind to go forward with some Theme based designs , e.g. - Characters from "THE STRANGER THINGS" series , from "MONEY HEIST" series etc.
We will discuss more if we move forward in this. I hope I have given you some basic idea about my need. Attached some sample images for your understanding.
