Accept that everything you do will always be missing something in your eyes, and move on.
I'm not writing some masterpiece that will stand the flow of time and it will be seen as a groundbreaking work. I'm making some weird comic about lesbians in space.
I'll have to agree with @PapaDom
Most of your threads feel like you keep asking people if you should continue, or are still looking for a perfect answer that will solve everything. But, the answer will probably come from yourself eventually, not from someone else.
Like, i understand the desire of perfectionism or watching creators you like and feeling your stuff will never be at that level (happens to me every time i see artists on Instagram, my art looks like total shit compared to them).
But at the end of the day, is just another comic on the internet.
I think the real question is
"It's a webcomic worth all these problems and doubts it seems to be causing you?"
At the end of the day, It's not the cure of a disease or something that may stand centuries like the painting of the Sistine Chappel and i haven't heard of anyone gaining the Nobel prize of webcomics.
When people take webcomics too seriously, always remember this: WE SHARE THE SAME MEDIUM AS SONICHU lol.
