MY SPACE ART

In term 2 in room, five were learning about space so  I came up with the idea to make these master peace. It took me only two days to complete it with my mum. It is a recreation of a video game map called fortnite.
I liked making it because there were lots of ideas when I searched it up.
The hard thing ab 8gout it was gluing the meteor to the map.
My next steps are to make what it looks like and make bigger models of the places.

what should I do to make it better?
