Hey there. I heard you wanted a review. First one I've done in awhile, so I might be a bit rusty, but bear with me. For reference, your total score when I was tabulating was 84/100.
-Excellent sample manipulation. Probably the most realistic I've heard out of all the samples.
-Excellent sound effects around the 2 minute mark, nice flanger, nice high-end SFX. Not sure how you pulled those out, but it's awesome.
-Excellent ambiance overall, you really manipulated the samples to paint a picture.
-I do find it very impressive that the second half of the piece is the same chord progression as the first half.
-So, smaller things first. Ending wasn't that interesting or conclusive. It just basically ends, sounding more as if ideas ran out than it was intended to end there. This ties into the next point, which is...
-Flow. I've actually written some things about the flow of music, and this is one thing that your piece somewhat suffers from. It doesn't feel like it has a particular direction to it - rather, it feels like a few atmospheres that were strung together with some compositional theory, like using the same chord progression twice. I recognize that making a proper melody out of the samples is difficult, but certainly possible, especially given you submitted this with a full 7 days more to work on it. There was far more development that could have happened in this piece, which just... didn't.
-Mixing. Yeah, this shouldn't be too surprising as being a significant factor. It hit basically everybody in this contest, so here are some specific comments on yours. Lot of overly buried sounds around 1 minute in, partially simply due to the amount of brass. There are some bass hits which are hard to hear and a lot of the detail of the higher horns is buried as well, particularly around 1:25. Closer to 2:33 the lower brass gets very muddy. This is also partially due to using the same sample, as that can cause phasing and distortion due to having the same waveforms playing.
Overall: Again, 84/100. Biggest things were the flow and mixing. Flow is highly determined by intention of the piece, but can still work very well. Mixing could simply be corrected with more clarify of individual instruments.
