Welcome to the forum. For a newbie your work seems good to me. Some things to improve (imho):
1) Balloon layout. Try to arrange them so that the speech is easy to follow. Theoretically the layout is always from left to right. It helps readability.
2) Dialogues: Try to avoid repetitions and don't forget punctuation.
3) Story. Working with AI forces you to use good images. Consequently the story (and dialogues) must be modulated on the images (usually it's the other way around). This is understandable, but always try to maximize the material you have.
4) Be strict. Choose only the best images you need for the story. It's not said that all of them have to be used, you can put the good ones at the end as a a bonus gallery. This, and a little bit of graphic editing, can help with stylistic coherence which is one of the big problems of images made with AI.
I'm curious to see your next work, this is very hard-core and I have to say it's an interesting style.
