you've made a lot of fascinating composition and arrangement choices that i think really sell the concept well! i love the call-and-response of the piano and horns in the beginning, along with the key changes and instrumental palette alterations as the theme continues. the section starting at 0:50 is so good... ^_^
it'd be amazing to see you work on this further; with the realistic instrumentation, it'd be awesome to get some volume variations as the instruments play, or have some ornamentation on things like the piano!! well-done!
