Hmm...what to say..?
A straight ten, I can tell you that!
My mind is a little empty at the moment, so I can't comment on too much about the song, the words won't form...perhaps I should save this review for later, but good chance I'll forget about it then, so here goes nothing...
The intro gives away there's something good waiting for you right away, I like the fade in the piano, and the bass coming in at around :12 add to that.
The wind/breeze sounds fit in very good as well. At first I thought the siren was a little high, but it goes with the general feel of the song very well. There are no spots that feel crowded or empty, everything is balanced, and very satesfying to listen to.
I can't find any spots where I might be able to suggest something, you simply can't improve on this one :)
Hey, I managed to type something out after all, yay for me (and you of course), keep producing great stuff!
