INTERESTING string sound in the intro. It sounds somehow organic AND electronic at the same time.
I must admit I'm a tough customer as far as this genre goes, since I also produce trap hip-hop. That 808 is modulated VERY well, however, it's just not hitting as hard as you need it to, potentially because it's too far down in the mix relative to the snare and melodic/non-percussion rhythm instruments. I would turn it up and clip the crap out of that 808, as it doesn't sound like the sample is bad, just a bit flabby in the mix!
Your cinematic elements would 100% melt my face, IF that bass issue were fixed! They are well written and orchestrated, pun intended ;) It's just that the 808 is the foundation of any track and in this case it seems to be lacking a bit of gas. If you can't hear what I'm talking about, let me know what kind of monitors or headphones you're working with. I'd be interested to see if I can replicate what you're hearing.
Now, looking at your waveform, I see it is decently fat, but in this genre, it could probably be fatter. What you want out of this particular genre is an 808 that sounds STUPIDLY loud and clipped, followed by the snare and potentially hi-hat in terms of loudness. The pillowy kick should be subtle, in order not to make the 808 seem smaller than it really is. Lead instruments and other rhythm instruments play second fiddle to 808 and perc in almost every instance.
I also would have widened, chorused, and potentially made an ensemble out of your string lead. It sounds a bit centered and thin on the drop.
Beyond that, great sound design and really interesting to my ears!
