Gratz on the frontpage! ^_^
The mix is really clean - I think those multiband compressors really help add some clarity. The cute, pizzicato-y lead adds a lot to the atmosphere, although the string lines sometimes feel like they could've been shaped a bit better. For example, at :25 they oscillate pretty rapidly between full, rich chords and bass pedals, which comes across as a bit jarring. I'm also not sure the acid bass at 1:40 blends in well with the rest of the texture, and the bass is a bit too loud in general at 2:05. The bare-bones breakdown at around 3:00 is a nice touch, though.
At some point, I would've liked to hear some more dynamic melodic content from you. Most of the lead string and synth lines come in short, fleeting phrases that don't have a strong sense of continuity with the following one. I'd challenge you to come up with an extended melodic line that ends in a very different place (in pitch, intensity, etc.) than it began. It's an advanced skill to have really memorable melodies like that, but it would seriously take a longer piece like this to the next level IMO.
That said, you've done a good job creating this ambient tapestry of sound here. Certainly one of your stronger pieces, and like I mentioned at the beginning, the mixing is especially well-polished. Keep at it, CF24! ^_^
