Read the synopsis and chapter 1.
In going to make this short. 639 words and a healthy chunk are used to talk about dreams and the sun.
Not to mention it reads like Dr. Seuss.
If you mean for it to be a child's tale, then it's great. If you are trying for a real love story for a mouse, then it needs to read like one.
You spend more time with dreams, the sun, the other mice talking about him, then the main character himself. And that's supposed to be the chapter that grabs our attention.
Be well.
This is straight facts. It reads like a child's book and/or a Bible story. It's like... There's no story here. It's just a montage, as far as chapter one is concerned. It's telling everything instead of showing some things.
"This is how everyone feels about each other". It's not engaging. And the dialogue is just... Meh. Those are some entitled sounding slaves. I know there's some desensitization of that word with web novels, but still. Slaves talking mad shit? I guess. That attitude would make more sense with lowly servants. But that's part of the problem isn't it. What kind of slaves are they? What kind of classist society is this? Can't just throw out that word as if it's all encompassing and expect people to just nod.
I need to see scenes. I need to see action. And not in the zoomer brain rotted way of "if no pew pew why bother". Stuff needs to move and happen. Telling the motivation of your protagonist right away? In a vague void of narration? Not a good look for me. I need to see that in action. I need to see the
character in action. I can't just buy into it with just this. There needs to be more... In general. Descriptions, scenes, and character are lacking. This needs to be beefed up in every way.
Don't shortchange your first chapter. I'm not for filling word count out just to make it seem long and reach a quota that everyone else reaches. But if you can't make enough stuff happen with less than a thousand words, then you need to expand. And I'm saying this because I've been there and I continue to write less than what should be on the page.
Also that cover is much better than what was there before.
