Great job for your first track! Certainly way better than my first track by a long shot.
Some constructive criticisms I have is that:
The intro ambient rain sound effect is a bit loud in my opinion.
Adding some riser effects, or even just white noise with volume automation would really help the parts of the song flow together, as I feel like they just kinda come out of nowhere at parts. The buildup for the second drop sounds pretty alright tho!
In the second drop, I feel like the chords and bass are kinda muddy, they could use a bit of tweaking to get them to sound cleaner. Maybe the bass is too loud? I'm not too sure, but something's a bit off.
Some things feel like they could use reverb, they feel a bit too dry.
That's all the criticism I have for it! But don't feel too bad abt those things bc its your first track, you did really good, and I can't wait to see you improve with time :)
