I wasn't sure whether to post this or not as I have a feeling its probably one of those sources that has been done many many times, but fuk it.  Archangel inspired me to do some orchestral arrangements and I thought I'd kick it off with a source I truly love. 
Its really early days.  Some things I'm aware that need altering: 
 
The string sequencing at the start 
Trumpets at 00:44 need some more humanizing 
I need to actually learn the guitar part properly  
Write a drum part that doesn't loop 
Mixing at 1:51 needs cleaning up as it gets a bit too busy 
2:15 onwards is just a skeleton arrangement.  Need to flesh it out. 
 
There are many other things that need sorting I'm sure, but that's why I thought I'd post it here  
Any help, as always, is much appreciated
