Like the olskool synths in the beginning. I think maybe you could apply some LFO modulations to them to sound a bit more lively. The melodies are nice and dour, everything seems to flow well into your build.

One thing, your drums sound like FL stock or something, and they struggle to peek through the shoegaze reverb. I would cut below 250 hz on your reverb wet signal if you absolutely must keep it, maybe even employ something like a side chain with the degree of bleeding.

To do that, I'm not sure what program you have. I have mixcraft. I apply a simple EQ over top of whatever tracks I want to side chain, and then use an audio controller to duck the volume. It takes less CPU than using some of my compressors, I've found, and achieves the same result I'd get from manually ducking. I'd use the snare and kick respectively as signals there.

Your writing and arpeggios really shines, despite the boxy low reverb bleeding. You're quite talented as a composer.

For drums, there are lots of free online drum kits and samples. If you'd like a few, I can go digging through my library for recommendations. Saudade snare and a sampler that supports multiple files works nicely. Dark Kick is a staple of mine. I occasionally use crash VSTi, although it has no round robins. Cymballistic is a nicer, if hard to understand cymbal vst, with many options. I haven't got a favorite for toms. You could probably rip them from MuseScore and use a sfz player like Plogue's sforzando. Somewhere I have a tutorial I made for that in my news posts, where I did it with Muse Score drumline.

Oh, and I forgot to mention, KSHMR Essentials Kick is a free all in one processor I recommend using on your percussion. You can apply saturation, stereo widening, and transient shaping so your sounds cut through, all in one, as well as add mid or sub to your liking. It allows you to see the waveform right there in box. There's a paid version that has more options, but the free version is fun to use on just about any single instrument.

Ultimately, I enjoyed the piece. It's well written and progressed, with clear themes. I think some more force could be derived if there were a clear bassline, rather than the low saw that sort of sat there in the mix. I think you're onto something though. It's only up from here. PM me if you'd like recommendations for synths, collab, etc :)
