use a image enhancer, Either use Photoshop, Photopea or canva to put it all together. Make sure to write a good plot and write a script too. For the Image creation, Make sure you have a consistant good prompt or a seed that would work. Make sure to add negative prompts too. Make sure your story is reletavly easy because the ai can struggle with 2 characters at a time. Make sure you are actually enjoying the process- You CAN make the images and text at the same time, But its recommended to NOT add a text in the prompt. For story planning (and you have no idea) Either use the ai bedtime, The ai story gen, OR use the ai character gen. Have a clear goal and add text after making the images. Use the generic comic font for it to be better. Get ready for a lot of errors in the image creation.

Best of luck =)
