A Good Effort
The first 5 seconds of the song is my favourite part. How it starts off slow then the how drums come in and get it rolling is really smooth. The rest of the song, however, even though in the same key, does not mix very well. Hardly anything sounded bad, but hardly anything sounded good either. But I did like the classical part (which still did not mix perfectly, but mixed better than the other sections).
In the classical section there is a track of chord progressions which has a synth sound rather than classical. If you're going to separate this project into separate sections, it helps if the sections actually fully match the descriptions. :P
The "whole shebang"... well, that sounded terrible to be honest. At least you separated the project into different sections for the rest of it though.
To the participants: to be oblivious of your teammates' parts, only aware of what your part sounded like, and for each member to produce something that when mashed together did not sound bad is an extremely good effort. I admire how some people took the initiative to create a melodic lead as others sacrificed showing off their skills in a technical melodic lead but produced simple harmonious chord progressions to improve the overall sound of the song.
In conclusion, this project turned out pretty well seeing as how it was produced and taking into consideration the rules the creators had to follow. A mashup is never going to be truly amazing as a written composition but this was a good effort.
