Emotionally Rich Buildup & Release
Seeing as you reviewed my pieces, I thought it only common courtesy to return such kindness :)
First of all - I love the flute at the end. Oh it's gorgeous. I am speechlessly envious that you have one, and can play it. It has a very haunting feel to it, a brilliant way to end.
I gave a 9 out of 10 - so what can be improved, you might think? Well, when I listen to pieces like this, I sort of get a feel for what would give it more of a 'cutting edge' so-to-speak.
I think at the beginning, if you added in a low, 'wind-like' slightly distorted synth [that plays very low deep notes & fades in gradually] you would add this nice bass layer to the whole piece - it would add a very subtle feel that would work brilliantly I think. It would also set the tone of the piece nicely, since the beginning sort of feels like there is a 'gap' in the bed of sound.
In fact the sort of sound that I mean, is the one that you used from about 2:30 onwards :) [I just noticed that on the 3rd listen through.. xD]
All in all, well done. :)
