Track 1
Birds - maybe a little too frequent to where it doesn't sound natural due to your track having it as a more constant stream of chirps, rather than more delicately chiming in.
Compositionally, it's maybe a little repetitive in that it doesn't develop or transform much. This is one of the biggest challenges of ambient music, and I'm glad I made a jam focused on ambience because I myself realized it wasn't as easy as I thought!
Track 2
I like the bass percussion. I want the percussion to be spatially farther away. This one so far seems to develop a little more in a way that allows the repetitive theme to not be as grating.
Track 3
So far my favorite. I feel like this one captures the vibe the best.
Overall - thought the footsteps was a fun addition to really give you that feeling of walking. When I look at the waveforms on all three of your tracks, they are all very constant. Having moments that swell and fall, in my mind, is one of the things that makes solid ambience, where moments don't linger too long.
The mix is nice and clear and spacious, and there is a lot of creativity here with what elements where used.
Well done! :)
