you must be able to compose a wide variety of music, ranging from light-hearted background music for more casual or comedic moments, to much more story driven hopeful, emotional and dramatic pieces. The music  should enhance the storytelling and make key moments even more impactful. I would recommend taking inspiration from other popular sci fi media like Interstellar, Final Space or the indie animated pilot Godspeed, as well as bands like Oasis or Radiohead for more character focused moments. Also, remember to be creative and think outside the box!
