There isn't enough material to give a comprehensive review, on characterization and plot, but I personally would cut out the prologue.
These narrations rarely work and the world building information would be much better presented if it was naturally revealed throughout the course of the story.
Aka: we infer this from the setting, or from character interactions.
Since the slice of life scene are fairly standard, that is to say, we can pretty much predict from the get go their personality archetypes, and lifestyle/occupation I'd show these scenes after a major event or interesting scene happens, to initially hook the audience for example a battle, a chase sequence, a death etc.
I'd also try to make the SOL scenes more interesting by using this time to reveal more aspects of world building, if applicable.
Or emphasis a character quirk or show an interesting trait they might have, really anything that sets them apart from another story's protagonist.
Does he draw? Does he read books on pagan gods? Does he compulsively text on social media? Does he struggle with his magic god powers? Then show it.
I wrote some threads on writing advice which you can read here:
you can also watch my editor's YouTube videos, the videos go comprehensively into the technicalities of writing fiction writing, his videos focus on writing in anime but a lot of it can cross over to comic writing also.
Also, yes upload your comic on Tapas. It's a good idea to post your comic, in as many platforms as you can.
I hope this helps with your story!
