The execution

I'm trying to design a t shirt. This is my first time and I don't have knowledge of the parameters of such a task. I'm hoping there will be someone who has experience doing art specifically for t shirts and for screen sprinting businesses use. My idea is simple. Im looking for an illustration for the execution of Paul in the Bible. Not too much detail just a rough outline of the scene. I really want to give leeway to the artist to use their own creativity. But an example I'll upload of about what I'm looking for .
