Happy birthday whenever it arrives/d!
I remember back in the 90s when I first showed my work to a friend who read widely outside the fantasy genre, and he gave some unsparing feedback on the melodrama, stereotypes, and lack of character development in my work–and yes, sentence structure and punctuation. It was a gut punch.
It was also incredibly valuable. I changed my writing in response; I doubt my critic friend would say I’ve completely escaped any of those bad habits, but I’ve at least mitigated them.
You’ve had some even harsher comments, but I hope when you pick yourself up again you’re able to adapt and keep going.
The style guidance preferring short, concise sentences, minimal adverbs, and sparing use of semicolons, dashes, and ellipses has been around for about a century. It’s a good lens to be able to apply to your work; even if like me you don’t want to sound Hemingway-esque, looking at your work in that light can help you be more selective in your adverbs, vary sentence length so it’s not all long compound sentences, etc. The ultimate effect would be to make your prose clearer and more accessible.
