Graphic novel???

I have been wondering about the format of my book. I'm not sure it will be a novel, but naybe a graphic novel. I can sketch, but I am not a graphic artist. 

Maybe it should look like the angel's personal journal with her sketches in it. I think the art needs to be amazing though...

Here is my attempt at a page with sketches. I would love feedback! Feel free to comment below. 

A man touched by darkness asks an angel to pray with him. It takes nerve to ask this. Desperate pain threatens to burn him up. The angel is confused. He had just told her he was turning his back on her. Turning his back on the light.

Now he asks to pray?

The angel gently nods her head. That is why she was sent to him.
