Ale, I am of the opinion that first a thing must sound... then the rest follows, in the sense that if it is correct and doesn't feel off...

True, thinking about a group of ten, I had a problem perhaps more than a double string quintet... assuming it is used, winds for sure.

In fact, compliments also on the IT setup

In general, string orchestra, little of their main characteristics (aside from some pizzicato). You could have used at least vibrato and tremolo somewhere.
Question, are the slurs phrase slurs or were you thinking of bowings?
I would have handled the fills differently, with some dyads... I don't see space for harmonics; in short, you didn't create a "musical" opportunity.
The use of divisi within divisi seems to me to be handled in an un"structured" way in the sense that there doesn't seem to be a design (or even musical) to "justify" them... they seem a bit used out of necessity.
Regarding individual instruments, particularly the management of pizzicato
Violins, for the unison parts in the "divisi" couldn't you make them play by indicating different strings... so as to enrich the melodic line? In the end, it is the theme.
In cases like the divisi at measure 89: why do you double the Bb? It's the third of the chord... better other notes, no?
After the divisi, I would put them together
Violas at 86, divisi is missing if these were your intentions
cb: between 12 and 13, for example, you don't give him time to switch to pizz... put a G quarter note, it's just a doubling of the vc.
cb: at 79 if you put the notes this long, a double bassist will play them with the bow... pizzicato notes should be at most a quarter note, otherwise it is ambiguous and you leave time (also visual) at 85 to pick up the bow again
Obviously said by someone who doesn't claim to know much, but these are just types of things that in my opinion could be improved (or where I would work on them), most are just about "calligraphy"; in my opinion it is important, otherwise when you give the parts to the orchestral players you spend 2 days explaining what to do... and consequently higher costs for the performance.
