well i made a string chords (orchestral strings) then i layered it with pads to add some atmosphere then i made a short but uplifting electric guitar melody to emphasize more emotions to the music, then i also added some whistle to carry the electric guitar melody. Then lastly i added some glitch sfx and cymbals with a little bit of reverb to spread out the effect, and also i automate the strings to control the volume. That's all hope you learn something from REALM💜☺️
