I like the ideas, but I think if it may be better to use softer instruments, which would make the clashes less jarring. Also yeah, look into sending your midi into a DAW! If you do end up doing so, some good free orchestral libraries i'd recommend are Spitfire LABS, and BBC Symphony Orchestra Discover (google BBC Symphony Orchestra survey, they send it to you two weeks after filling the survey). I'd love to hear this with updated samples! It definitely matches the theme though
