I was just swinging by giving this one a listen from the link on the front page. I thought I'd take a quick look at the comments, and seeing that negative bit motivates me to write something.
To get to this level of presentation and precision, and knowledge of musical dynamics takes an awful lot of dedication and willingness to learn.
Also, criticism is always a dish best served consructively, or frankly, you end up coming off as jealous, or perhaps a bit jerkish at least.
The good of this piece greatly outways any of the small inadeqacies which don't mean a lot when you sit back and appreciate what is good about it. And I'm sure if you ask the composer, they'd be the biggest critic upon themselves about it. People submit remixes, but from my point of view as a musician (perhaps a bad one!) a mix is NEVER finished.
