Beginning is giving strong Toby Fox vibes. Love the ambience you got going on. At around 0:28 the sample cuts off early and for a moment there's no sound playing, which kind of kills the ambient mood you had going.
Following section is nice, I would've liked to hear some more building off of the previous section, because they sound almost exactly the same. Again there's that brief moment of silence going into the next section which I don't like, but the drums make up for it; they go pretty hard. They get a bit repetitive after a while, and a cool melody line or something could really hit that last section home. Transition to the ending feels quite rushed, and once again there's that annoying brief silence going into the outro, which I do enjoy but wish it was less disconnected with the rest of the track.
Overall, you did a good job with this one, but struggled with arrangement a bit. There's three distinct sections, but they all feel disconnected from one another and could benefit from some cool drum fills or FX. 7.8/10. I look forward to hearing more of your works!
