Weironara1006 There are various reasons why peeps don't comment. Reading is a solitary activity, so if the story is engaging it might not get comments.
Comments may break the reading flow for a person. Or peeps are shy. They just want to read. So they won't comment.
A way to gather feedback for development is secondarily.
Some methods I've used/use.
Compared similar stories and how they're written to see if there's areas my own story could benefit from writing it differently.
Read up on some how-to writing articles from a lot of experts. Many free articles are available on the net.
Read books by English authors as if I was doing a constructive review. Analyze it to pieces for my own learning.
Revise story, learn, revise again. Repeat the process until my story starts to attract some chatter from organic readership.
Also, I've been involved in some writing groups around the net.
I cope with the silent readership by learning more about the craft, experimenting with techniques and story ideas. I keep writing.
Keep at it. And congrats on writing your first novel.
