i'll be honest, for a full flavor tune this doesn't feel that cohesive. the transitions aren't great, i'm getting whiplash from all the sudden changes. the sound design is alright but feels rather tacky and cheesy in places, especially the dubstep basses. the orchestral part sounds alright, but the riddim part doesn't; the gun pattern feels stale and too consistent, the gun sound itself isn't great, and the way the lead is offbeat in that part sounds questionable
for the transitions i'd suggest maybe teasing later sections in earlier ones, whether through reusing melodic figures or putting lowpassed sections in the background of other ones. i imagine you'd do this after you have the base sections written.
for the sound design tbh they sound too outdated and preset-y; i'd look into sound design tutorials from established modern producers and learn from those. i believe subtronics does those sometimes, virtual riot has before, and agony is another prod i like. you can also learn techniques for things like arrangement and flow from them
so yeah, it's alright but could be better. i hope my advice helps
