The Preacher - A Comic Book Character Concept

I have had a comic that I've wanted to draw for a very long time, but I really have no idea where to start. Finally, today, I've decided to start it again. I had already made a few drafts of my main character before, but I didn't find them appealing. Today, I tried to draw the main character again.

Story Plot:

It is about a devil who accidentally broke his horn and wasn't allowed to enter hell anymore. This devil is a second-generation devil born on Earth. He has already heard about God but has never met Him because he was not part of the rebellious group. With nowhere to go, he took his chances to beg God. To his awe, God answered back and told him that if he continuously changes and saves a million souls before the second coming, he will be pardoned.

This is the start of the journey of the Preacher, a semi-devil who battles his former allies and stops them from causing evilness in this world.

Back to the drawing. Since I'm not really good at drawing, especially human anatomy, I've decided to use "Pose my art." It's not an AI tool; it's a tool where you can manually pose a human body and view it in different shots.

I uploaded it to Medibang and traced the body, then colored it. These are some of the progress shots.

Please comment on the plot of the story if it is good, and do you have any tips on how I can improve my character? Does he fit the story that I want to create, or should I make it anime style?
