First, I would change your summary for the comic. I know you want to be self-depreciating, but I don't think it helps. This summary is the first impression folks get of the comic, and its good to have a little confidence. Even if you said something like this,
"My name is Sara and this is a collection of my daily musings. Slice of Life/Humor"
It makes the point that the comics are short, independent of each other, and are meant to bit relatable or funny snippets.
I wouldn't point out that the art style changes here and there, if you really feel the need maybe in the first post put, "My musings are an experiment in thought and style, please don't adjust your screen some variation from comic to the next is normal." It makes it sound like your change in style is intentional and fun and less like you are confused about what you want from your comic. It's OKAY to be have different vibes for each episode. It's unique and an attractive part about your comic, just own it.
My personal preference would be for the images themselves to be a bit smaller so I can see most of the comic all at one glance rather than having to scroll, but its not necessary.
I enjoyed what I read so far. You have a ton of potential!!! Just show a little confidence, and keep up the good work!
