Hello, I thought your first chapter was strong. I felt for your characters, I'd have to say, Novus's mother was very real. To have to take care of the household and then see her child leave is definitely hard. Your first chapter does well to draw in your audience and I can tell what your targeted audience is.
Your writing style is definitely your own, I've never seen dashes used to indicate speech before and it's very interesting. It's your stylization and choice and doesn't get in the way of your reader getting used to your writing.
As for your cover, it's absolutely beautiful, kudos to your artist!
Your description is a bit wordy but you can fix this by it out in paragraphs. This can reduce the strain of the reader's eyes and help them separate information. For example, where you begin writing about the low-born mage, I believe that would be a great place for a space. Doing this will make the description seem shorter than it is and make potential readers more likely to read the fill thing. Anyways, well done! Congratulations on getting so far in your web-novel!
Here's mine if you are interested although our genres greatly differ! Mine is drama, teen fiction, lgbtq+ hehe.
