Final Composition Ideas - Update 1

For my final composition, I will compose my music for the train in the museum, specifically how the rails were built by workers. I have a few ideas on which instruments I want to use and they are an electric guitar, a male choir and a few other non-instruments such as pots and pans. The electric guitar will be used to provide harmonics and to create train noises, as for the choir I depict an idea that they will "hmm" chords representing the men working at the rails. Currently, the pots and pans are a 'maybe' to create percussive sounds to create the imagery of rocks being mined.
