Very cool ambiance, nicely crafted. Like the other says maybe only some synths were  a bit harsh and second track could've tone down couple of mid frequency to make it breath a litle more in the mix but other than that, great soundscapes with really nice moments. Good job.

Cool composition! that synth really hit, some bit harsh but it just fit the ambience you trying to convey.

These are really cool ambiences!  This kind of music is difficult for me to compose, but definitely taking notes here if I ever decide to do another jam like this.

You have some very cool sounds, using inharmonicity really well to create a sense of atmosphere.

Some of those synths get a bit harsh - managing higher overtones to create atmosphere can be tricky.

It's still a really cool vibe you created here. I like the microtonal whistle sounds in the second track quite a bit as well. This is also done well.

Awesome work!

From 2:12 onward in the first song, I suddenly thought, 'Lost City rave' would be such an awesome idea! You really nailed the ambiance—great work!
