Great song, pleasure to listen to.
-Critiques-
The "ahhhhhh" vocals' reverb could have some stereo effects to it so that it dissappears into the rest of the song more seamlessly.
The crash's high frequencies seem a bit too high. When it's played with other instruments, it seems to clash. I'd even say it's a bit overpowering. It SHOULD stand out but it needs blend in a bit more so I suggest turning down some of the higher frequencies on it.
The high hats sound a bit low in quality, as if they've been processed at a really low bit rate. Maybe you should use some different ones or synthesize your own.
There really isn't anything special about this song. It's all very generic sounding and plain. It needs a special spark that sets it apart from the rest. A reason to exist. What other aspects of exhaling can you incorporate into this song to make it more special? Maybe something about inhaling. Maybe record someone inhaling and use it before you start the song. You could even incorporate some lyrics.
Your song lacks sub bass. Your kick is punchy but, there's nothing else in the low end that complements it. It kinda makes this song feel empty. In contrast, there are a ton of thing in the high frequency spectrum of the song which makes the song unbalanced.
Also because your song is about exhaling, it needs more build ups and drops. Automate the volume of your instruments and add some more instruments at ONLY the buildups and make them epic.
Actually I feel like you should learn more about reverberation and how you can incorporate it into your songs to full effects.
Make sure you don't have frequencies clashing with eachother. Try to EQ when necessary.
You claps and reverse claps lack reverb. You could use a reverb with a really short gate on it to add presence.

Concept of the song (exhaling - releasing)
Instrumentation was nice. You had a wide variety of instruments in this song.
4/5
Good effort and good luck in the future! :)
