Hi! :D
I got to listen to your tracks! All three sound very "spacey" and "open", and that's a cool thing that you showcased that very well within your submission. Of the three, the one that did it the best was "003 Bubble Space". (That one was also my favorite! :D) A tip for writing ambient though:
If you don't want a melody, or perhaps have a melody that overpowers the accompaniment, keep the other elements present but not too fast. If that's what you were going for, then disregard.
If you do have a melody, but are worried about it being too outside of the "ambient" feel, don't move around as much, or simply slow down. (This one doesn't really apply to your tracks, but I still chose to mention it.)
If you do want to have parts in the track that are fast, or "layered" with lots of voices, consider adding a section where the listener gets a break from that. Perhaps where it's just bass and drums, or bass and a softer lead if not the same one, etc. Some ambient music writers know to implement this when a track might need to have a contrasting section so that the listener won't dread hearing it for too long.
You have such an amazing selection of voices used, and the soundscape sounds so professional! I really liked it! Congrats! :D
