Mellow, ambient, with a hint of space rock. That entirely suits my tastes. It also reminds me of a 90's computer game throw-back, like something that could have been included in Chronomaster or Welcome to the Future. Good job! Also, I like the pictures on the youtube video. Very complementary and relaxing.
I've one criticism, and that's the peculiarity of the, um, noise that sounds like a muted china cymbal (I'm not sure how to properly designate it). The speakers I was listening on have no capacity for bass, so the fact that I'm picking on that may just be the result of my bad speakers. Still, in a piece that's characteristically flowing and spacey, the curt quality of that crash, which is central to the piece, sticks out a bit. I just felt like it should be either lengthened or downplayed a little.
That's all. And, yeah, grain of salt since I'm not by any means a composer or music expert. The most I've ever done musically is march in drum line in high school.
