Wow man!
I thought you really wanted us to skip the most important part of your job! :)
Nice intro in fact, with a gloomy atmosphere and all.
Then comes the second part, your melodies seem fine, taking back a bit of the atmosphere of the intro.
But when I think it's a little too messy in the end... There are the strings coming, and then horns and it get tangled with the rest.
Also I would work on the sounds differently, your mix is too shy! And it seems you've got a huge compression on the master channel, because everything seems flattened.
Sorry if I sound a bit severe, it's just that I'm French, and sometimes I don't realize what I'm saying in English! ^^
Anyway, great job on the structure and the melodies, but try to clean it up make it sound clearer!
