Glad you managed to your submission done!
Feeling some Halo inspiration in this, the vibe is great, especially the more ambient parts are really nice.
On the Storm Colossus part, the very chaotic tension feeling is nice, but to me it felt that it lacked a good low end, maybe it could've maybe been a good place to add some low percussion to amp up the tension and help add gravitas to the colossus.
I agree with muttzilla on the reverb, although I guess its mostly the string sections that feel a bit disconnected from the rest since they're a lot more focused and bright sounding compared to the solo violin and pads, which are more ambient and distant sounding (at least felt like that to me)
Playing around with removing some high end with an EQ maybe could've helped with getting them to blend better spatially, since even if you add more reverb, the brightness of the sound still makes them feel a lot closer compared to everything else (not a production pro though, so take this with a grain of salt 😉)
Good job!
