What you got so far is pretty cool man, i love the organ breakdown at around 2:30. I feel like the drums are missing a more pounding kick or some cymbal/hit hat hits in there to brighten them up. Though just as a suggestion, its definitely not needed. Otherwise i think it's a pretty solid composition everything seems to fit together well, though i might layer in some added synths or low frequency bass to add more depth or something. Keep the storm idea for the song, i get that vibe for sure. If i were to suggest a title "Brewing Storms" might be cool haha. Anyway, cool stuff man keep it up!
