Time to break out the big one
Time for my first big review of the new year!
First off, the wind instruments are great - simple but they really add a lot of dimension. Very trance-like build up and there's a lot of action going on at once here, no wonder this has had such high acclaim.
Now, I'm not sure I can support the switch to piano around :45ish because it seems to make very little effort to return for another 45 seconds, and one time instrumental insertions are just not my idea of a good use! But that's just me, and I'm sure others feel differently. Personally I believe that you needed to combine that a bit more instead of keeping in separate segments, perhaps have them switch more frequently (every few bars?) to create a better dynamic.
The song is very simple, but some would say this is a plus, so I won't hold it against you - it's still very well constructed! I have to say that I like the orchestral instruments thrown in, but they could use a bit more work on placement in my opinion.
Well, look at that, that wasn't a very big review. Oh well, start off with baby steps :p
