*Clicks Tongue* Noyce. ( ͡° ͜ʖ ͡°) This is some pretty good stuff for a first upload. Also very clever of you to make your first upload ambient, you don't need a lot of stuff to make good ambient, you just need care for your work and some knowledge with synths.
Anyway, this is pretty good. It succeeds in creating an atmosphere which is the most important thing to do in ambient. By keeping the atmosphere airy, but warm, not harsh; you've created a track that's comforting. The synths are high and bright, creating an optimistic sound nothing is too sudden with use of attack and release.
However, I do have one problem with this. It's slow, but it's a bit too slow. Here's where the main challenge comes with ambient, you've gotta keep it relaxing, but somewhat exciting. I wouldn't expect anyone to nail that balance on a first track, so don't get yourself down, but that's the one thing keeping it from 5 stars. I think this would've worked much better as a longer song so it had more time to transition so you could create an environment with your sound to keep it interesting but calm. Still, amazing first track 4 stars.
I'm not scouting you yet, because this is your only song, but if more comes I probably will. I have my own little system I use to decide to scout people
If I rate something 5 stars: 1 more upload of 2 or more stars
4.5: 2 more uploads of 2 or more stars or 1 more of 4 or more
4: 2 more uploads of 2.5 or more stars or 1 more upload of 4 or more
3.5: 4 more of 3.5 or more or 1 more of 5
3: 5 more of 3 or more or 2 more of 4.5 ormore
2.5 - 0: unchanged opinion
'course I break the pattern if I feel it's necessary, but that's what I tend to do.
