Okay, I just got done reading through everything you have so far! First off I want to say, I think your characters, art, and dialogue are definitely your strongest points. I enjoyed the humor as well! You're absolutely doing a lot right.
In terms of some critiques, I do have a couple of nitpicks.(Take these with a grain of salt, I'm only one person with an opinion)
1) There's occasionally some weird things being done with the formatting/speech bubble placement. I found the flow of this section in particular to be a little disruptive and confusing.
2) The amount of gutter space also felt like a problem in the beginning but I see that by later episodes you fixed that and that overall, it's working much better! It's probably worth going in and fixing the gutter space in your earlier episodes to match since the first 3 episodes are usually what people look at first before deciding to sub or not.
3) Location changes were going over my head a lot. It sometimes took me a second to realize when they moved places or a flashback was starting. I feel like an easy fix is just adding more establishing shots. I know backgrounds are a pain but throwing the occasional establishing shot in there will not only help make your world feel more real, it will also help break sections up/indicate the location changes better.
Overall, great work though, I think you're starting off strong! I genuinely enjoyed reading it so you earned a sub outta me!
