oh yes! Inside is one of my all time favs. The computer heads reminded me of that. I felt you could explore more the connection of music and the world, just throwing ideas here: maybe explore the direction of isolation, music & longing for some purpose.
The music bit can be explored more for eg: like Max running towards the song in the Stranger things se4 - music helping bringing her out of a deep stage of apathy. I believe Musical angle can be a great usp for your idea & the computer heads too symbolizing some disconnect from reality
