So, just took a quick look, and...
Really, the big problem I see here is what you have written is a script, not a narrative. There's a whole bunch of missing description that is necessary connective tissue. If this was a movie, that would be the production designer's problem, and if you had an artist providing lots of pictures to illustrate the text, that would allow you to manage as you are.
But, those aren't present. What you've got are your words.
First paragraph: What does the spaceship look like? How damaged is it? Where has it crashed (on a hill, in a valley, at the edge of a cliff, etc.)? How do your protagonists climb out of it?
Third paragraph: What does the planet look like? What is the temperature like? Are they in a lush forest, a fertile plain, a desert, a tundra, etc.? What colour is the sky?
You've given us almost nothing with which to paint this scene in our head. You've told us that there is a planet, and it has dirt, and creatures that might be considered cute. There's a lot missing here. You've got five hundred words here, but if I had to estimate, this should be around 1500-2500 words to do this chapter properly. The connective tissue and description are not optional - you need to add it for this to work properly.
