hmm not bad!
its still needs some mastering as some parts peak (vocals in some areas) and there isnt a strong enough bass, if any. Im glad this is a beta, so i can offer you some constructive criticism.
around 1:16 where the violin comes in, it would be an amazing point to build up the song. the brass and vocals should be pushed back into the song as a bridge to the final build.
overall, its a piece that needs work, but all the parts are there. A good percussion section is what this piece needs. Crashes, timps, shaker, gong, etc. would be amazing for this piece.
overall nice job and i hope to hear the final piece!
