There's some great parts and some not so great
-:00 - 23 nice clean opening, the brass could use a bit of toning down (EQ)but nice fat chords.
:27 - 47 - the rhythm is off and distracting from those nice strings in the bass
:55 that transition doesn't flow - try simplifying it
Goes along nicely till 1:02, beautiful horn part there.
Some transitions between sections, i.e. 1:11 are rough but you can smooth these out
To 1:41 - starts out nice then the feel gets lost in some chord changes that are a little distracting
Att 1:43 -2:21 this is the strongest part of the composition, KEEP IT! Develop it.
Another rough transition at 1:21, then to 2:35 this part might be good on its own but it doesn't fit with what came before very well.
From 2:35 to 3:35 is VERY GOOD - could be a cue track on its own.
4:20 and on (repeats earlier sections) so all above applies. I really like these specified parts, suggest separate them out for several different cues. Oh - watch the distortion at 4:05 - 4:17

The mood is very captivating, suspense, relief, from stress to intringue, from calm to restless and I applaud your ability for creating clever transitions over all those parts in such a seamless way. To me, and I am talking with experience, the transition subtileness is my main focus because I do have a weakness there : you dont seem to have this issue, it all flows naturally with intelligence and creativity. So, whoever you are, you have all my respect for building such a complex piece. I can imagine movie scenes (chasing scenes ala A. Hitchcock)... so, Bravo !

Obviously there is some dynamite musicianship here
