it has potential
The story is amazing, and it has potential to become a great story. However, I notice you start often with I and then and more. When you do this, it can read a bit robotic and comes over easy. You can easily change this by using commas and signal words. You could also put more depths in the characters, you can do this by writing more detailed about their struggles, their personality and habits. Another thing is descriptions. They are like the glue to the story, you can use idioms for them to make it even more real. You can easily do this by writing about what their faces look like, the emotion in their eyes, what they smell and see. It allows the reader to paint a better picture. Like when Matto goes to the meadow, you can write about how the moonlight bounces off the lake and how he can smell the fragance of the flowers, maybe wolves howling in the distance, These are all little things but can easiliy give you 200-600 more words per chapter. For the rest the convo's sounds real, which can be a hard thing. your grammar is good too, for as far as I know. I'm not a native speaker, but I do not see any major mistakes.
