Very smooth.
Man, when I just saw the title "Space Ambiental Loop" I didn't know what to expect. The name itself just isn't very convincing that you're going to hear something worth listening to, but...this one works, and I really enjoy what I'm hearing. This could totally work for the beginning of a title screen, or select stage screen. Possibly even a character select screen.
The reason I give it a 9, is for two reasons actually.
1) I'd just prefer more composition, I realize that's fairly biased (in fact...it's VERY biased) but...I always feeling like I'm going on a journey when hearing this kind of stuff. The "ambient" genre - to me - is always based on the soundscape and complexity of the textures of the sounds you choose to use. It's all about creating an imaginative environment. That's just me though.
2) Well, the title was kind of a let down. lol, I'm not trying to be mean, I'm just saying that if the title were a little more exciting like, "Frontiers" or "Galactic Continuum" (considering it's a loop). :)
But what you've got here is great man, I definitely look forward to hearing more. :)
