Throwin' a review right back at cha ;)
Intro is extremely lengthy. For this case, especially since it's ambient, I enjoy it being a minute and twenty-some-odd seconds. It's enough time to get lost in the melodies and just relax.
Though, when put into perspective of the piece as a whole, it could definitely have been shorter and more consistent with it's presentation - and what I mean by this is that I hear that you're trying to establish your theme, but it kind of sounds like it's all over the place at times.
The only consistency is in your right hand play, but the left hand is kind of jumbling around on chords, both arpeggiated and non. There's a set couple that match, but then it kind of falls off at times (and I'm using these right/left hand markers to differentiate between the high and low octaves, just to make that clear).
After 1:30, the key-change is welcome, but the moments leading up to it didn't really help facilitate its change. The right hand went into it, but the left hand didn't join in for the follow-up. A build up would have better used at that point, if a follow-up didn't occur.
It's at this point that the piece really opens up, I like this section more than anything else around it. The only issue is that it doesn't expand upon its electronic-feel. A soft saw would have really widen the track; a couple other arped squares or triangles would have definitely been able to fill the space here. It also saddens me that the piano didn't really change up at this point. Variety would've taken this to the next level - changes in patterns, tones, textures, spacial and dynamic feel...
It is very calming, but the only problem is how monotonous it is. The improvisation at the beginning was nice, but it needed consistency. In the next section, you went to a more patternized state, which gave it consistency, but where improv would have helped it breathe and become much livelier -- the section that I like oh so much!
It would seem as if two ideals are happening, but they aren't meshing too well. That aside, it's a chill piece. Just a little more glue here, some elbow grease there and you got yourself something sweet.
