there is no excuse for rudeness of course.
what I could tell by your first episodes though, is that it does not look like you put a lot of care in. like how in the prologue, and even your Title Card that you use every episode, the panels are squished and distorted, which makes the text almost impossible to read and all the drawings very stretched. Thats not a good first impression.
like I said, it does not justify rude behaviour so if you think someone is actively attacking you, block them if that's a feature on the site.
Be aware though, that not putting care into presentation will attract more trolls, since they feel as if it's fair game if the author themselves "doesn't care" from the looks of it.
You obviously do care, or you wouldn't be bothered by it.
Being a beginner artist is always hard, but don't feel discouraged from making something and sharing it.
do be aware of your presentation though, if you can! Things like unreadable text aren't related to your art skill, and are easy to avoid!
if you currently draw on something like paint, I recommend switching to sometihng like Medibang paint pro! it's a freeware and it will allow you to use layers, so you can keep your sketch layer seperate from your drawings, and when you rescale your text, it also won't blur!
good luck, and keep your chin up!
