I agree with NahuPyrope on most accounts, including loving the song overwall, so I will just add where I differ below.
I think the snare could have saturation subtly added to it and increase the fizz of the bottom head sounding just a tad. Timpani hits on the start of bars could be slightly louder also. I'd prefer just a bit tinnier violins for lead lines, a bit more pronounced high mid for tenor brass on lead lines.
The low strings and tuba are sticking out just a bit in the mix in terms of verb -- having played live ensembles that is not typically how I expect them to sound in concert hall -- it really sounds as if the brasses are all in separate spaces if you want me to be real with you there -- but in a hybrid sense this is not so bad
Flute/mallet flourishes are not sticking out as I feel they should above the repeated stabs, just a bit more please
This sounds like changing your gear before setting out for an expedition! Nailing your stated theme.
Loop could be better executed perhaps due to coming down to just the snare. Perhaps would work better with a snare and crash??? Or tamb? Or simply a more accented snare hit with more room? The dryness of the snare is what is killing it to me. If you must do some audacity snipperoos to get it down, it works. IzotopeRX7 can trim the .mp3 auto encoded silence without having to render again, also, for perfect loops.
