First of all, thanks for doing so many reviews of creator's works here on tapas! Hope your page is successful.
I'm not sure how much more experienced I am, but here's my take on it.
This looks really good so far. You give an introduction, a goal, content, etc and have a good mix of locked and unlocked content.
Based on reviewing a good amount of successful crowdfunding projects/ko-fi pages in order to make my own, here are some trends that I see in a successful ko-fi page that might help your page if you include them.
1) A general benefit to help expand your horizons.
It might not be possible since it seems like you're a bit busy, but being able to open 1-2 commissions a month would help a lot. It opens opportunities to reach out to viewers other than your readers/fans, and you can definitely capitalize on your status as a professional publisher, writer, editor, etc.
Some ideas of quick commissions are:
2) Open up shop.
It seems like you offer physical copies of books from your publishing company, so maybe posting a few on your page using the shop function instead of posts. This would help your page look more official and helps show your status as a publisher. (People don't usually click on links unless something piques their interest) Also, I'm not sure if you're even able to do this, but offering to make physical copies of books at a lower cost might also be a good seller as well. (I might be wrong with this assumption though.)
3) Create a visible progress bar for a goal.
A goal towards something (maybe your next novel in your case) is a trend I often see in successful ko-fi pages. It'll help readers know what their donations are going to, and even pages that are just honest and say "I don't have a defined goal", but still show the amount of donations they recieve, are prevalent and seem to work better than those without one. I guess it's the sense of transparency that helps draw people in.
Anyways, take what you want from it since I don't think I'm a reliable source. If anyone says anything different, believe their experience over mine, but hopefully you can glean some ideas off of this.
