I feel like the main premise was good but not well executed
We don't know much about the characters and the first thing that shows us is a tedious trip, how would they extend the story? Leave some interaction with side characters that don't feel real and natural, they are basically there to stretch, again, because we don't know anything about the characters.
And the appearance of what could be a threat on the 1st chapter is too soon, and even after knowing it's a "normal creature", making it a familiar is too sketchy.
I think actual interaction between the characters, and interest in the dialogue would-be better than stretching for the sake of it, and the 1st chapter tells a lot about how will be the narrative.
Just my opinion, peace nerds
