Ambient...
Hm. First I noticed that the opening piano wasn't a very good sample. Its sorta muddy in the mids, which can get bad later, especially with the amount of reverb on it. I'd advise using an E-Piano instead, or a Rhodes type of thing.
Next, I noticed that the hats are a bit grating for a song that I'd want to fall asleep to. Try some reverb, and EQ out some of the fuzz.
I like that lower square, but the upper sawtooth kinda gives me a headache. It goes too high, and the progression wasn't catchy enough to merit doing that.
However, I like some of the ideas here, and it does mesh well in the end. Its just too short, and kinda repetitive. I guess we both have the same problems when it comes to producing...
Anyways, it was actually a pretty cool blend by the end. I enjoyed it. 8/10, 5/5
